From 70804e560b072df175a3406b45bdeb60f194efc7 Mon Sep 17 00:00:00 2001 From: Alexandru Ardelean Date: Fri, 22 May 2020 10:08:01 +0300 Subject: [PATCH 001/428] iio: light: tsl2563: pass iio device as i2c_client private data We may want to get rid of the iio_priv_to_dev() helper. That's a bit uncertain at this point. The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. For this driver, it implies passing the IIO device on the i2c client private data. The implementation of iio_priv() will not be affected by the rework/hiding of iio_priv_to_dev().

For the PMIC7-type PMICs, ADC peripheral is present in HW for the following PMICs: PMK8350, PM8350, PM8350b, PMR735a and PMR735b. Of these, only the ADC peripheral on PMK8350 is exposed directly to SW. If SW needs to communicate with ADCs on other PMICs, it specifies the PMIC to PMK8350 through the newly added SID register and communication between PMK8350 ADC and other PMIC ADCs is carried out through PBS(Programmable Boot Sequence) at the firmware level. In addition, add definitions for ADC channels and virtual channel definitions (combination of ADC channel number and PMIC SID number) per PMIC, to be used by ADC clients for PMIC7.

The major change from PMIC5 is that all SW communication to ADC goes through PMK8350, which communicates with other PMICs through PBS when the ADC on PMK8350 works in master mode. The SID register is used to identify the PMICs with which the PBS needs to communicate. Add support for the same.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

This also updates the devm_iio_device_alloc() call to consider the device object as the parent device by default. Having it passed like this, should ensure that any IIO device object already has a device object as parent, allowing for neater control, like passing the 'indio_dev' object for other stuff [like buffers/triggers/etc], and potentially creating iiom_xxx(indio_dev) functions. With this patch, only the 'drivers/platform/x86/toshiba_acpi.c' needs an update to pass the parent object as a parameter. In the next patch all devm_iio_device_alloc() calls will be handled.

In cases where devm_iio_device_alloc() is used, sometimes the parent device must be different than the device used to manage the allocation. In that case, this helper should be used to change the parent, hence the requirement to call this between allocation & registration. This pattern/requirement is not very common in the IIO space, and it may be cleaned up later. But until then, assigning the parent manually between allocation & registration is slightly easier.

This semantic patch also removes some comments like '/* Establish that the iio_dev is a child of the i2c device */' But this is is only done in case where the block is left empty. The patch does not seem to cover all cases. It looks like in some cases a different variable is used in some cases to assign the parent, but it points to the same reference. In other cases, the block covered by ... may be just too big to be covered by the semantic patch. However, this looks pretty good as well, as it does cover a big bulk of the drivers that should remove the parent assignment.

Since the devm_iio_device_alloc() [now] assigns the device argument as the default parent (and since this is the more common case), for cases where the parent needs to be different, the iio_device_set_parent helper should be used. That makes things a bit more obvious about the new behavior of devm_iio_device_alloc() and makes it clearer that iio_device_set_parent() should be used.

This automatic assignment is done in the iio_device_register() function. There is a fair amount of drivers that currently manually assign the of_node of the IIO device. All but 4 of them can make use of the automatic assignment though. The exceptions are: * mxs-lradc-adc: Which uses the of_node of the parent of the parent. * stm32-dfsdm-adc, stm32-adc and stm32-dac: Which reference the of_node assigned to the IIO device before iio_device_register() is called. All other drivers are updated to use automatic assignment. This reduces the amount of boilerplate code involved in setting up the IIO device. The patch has mostly been auto-generated with the following semantic patch // @exists@ expression indio_dev; expression parent; @@ indio_dev = \(devm_iio_device_alloc\|iio_device_alloc\)(&parent, ...) ... -indio_dev->dev.of_node = parent.of_node;

Non obvious changes: - struct ieee80211_ht_cap is different enough that I preferred to keep (and rename) it for now. - mcs_rate in translate_scan was not read after being set, so I deleted that part rather than using the renamed struct - WLAN_CAPABILITY_BSS is replaced with WLAN_CAPABILITY_ESS which is the corresponding one with same value Signed-off-by: Pascal Terjan Link: https://lore.kernel.org/r/20200609194848.166130-1-pterjan@google.com Signed-off-by: Greg Kroah-Hartman --- drivers/staging/rtl8712/Kconfig | 2 +- drivers/staging/rtl8712/ieee80211.h | 584 +----------------- drivers/staging/rtl8712/rtl8712_recv.c | 7 +- drivers/staging/rtl8712/rtl871x_ht.h | 2 +- drivers/staging/rtl8712/rtl871x_ioctl_linux.c | 13 +- drivers/staging/rtl8712/rtl871x_mlme.c | 14 +- drivers/staging/rtl8712/rtl871x_recv.c | 7 +- drivers/staging/rtl8712/rtl871x_recv.h | 2 - drivers/staging/rtl8712/rtl871x_xmit.c | 2 +- drivers/staging/rtl8712/wifi.h | 21 +- 10 files changed, 21 insertions(+), 633 deletions(-) diff --git a/drivers/staging/rtl8712/Kconfig b/drivers/staging/rtl8712/Kconfig index c62747c90968..8de26425225b 100644 --- a/drivers/staging/rtl8712/Kconfig +++ b/drivers/staging/rtl8712/Kconfig @@ -1,7 +1,7 @@ # SPDX-License-Identifier: GPL-2.0 config R8712U tristate "RealTek RTL8712U (RTL8192SU) Wireless LAN NIC driver" - depends on WLAN && USB + depends on WLAN && USB && CFG80211 select WIRELESS_EXT select WEXT_PRIV select FW_LOADER diff --git a/drivers/staging/rtl8712/ieee80211.h b/drivers/staging/rtl8712/ieee80211.h index dabaa8fd34fb..61eff7c5746b 100644 --- a/drivers/staging/rtl8712/ieee80211.h +++ b/drivers/staging/rtl8712/ieee80211.h @@ -14,14 +14,8 @@ #ifndef __IEEE80211_H #define __IEEE80211_H -#include "osdep_service.h" -#include "drv_types.h" -#include "wifi.h" -#include -#include +#include -#define MGMT_QUEUE_NUM 5 -#define ETH_ALEN 6 #define IEEE_CMD_SET_WPA_PARAM 1 #define IEEE_CMD_SET_WPA_IE 2 #define IEEE_CMD_SET_ENCRYPTION 3 @@ -102,162 +96,11 @@ struct ieee_param { } u; }; -#define IEEE80211_DATA_LEN 2304 -/* Maximum size for the MA-UNITDATA primitive, 802.11 standard section - * 6.2.1.1.2. - * - * The figure in section 7.1.2 suggests a body size of up to 2312 - * bytes is allowed, which is a bit confusing, I suspect this - * represents the 2304 bytes of real data, plus a possible 8 bytes of - * WEP IV and ICV.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information.

Instead of doing this in each and every driver by hand move this into the core. At this point in time, all drivers should have been resolved to attach/detach the poll-function in the same order. This patch removes all explicit calls of iio_triggered_buffer_postenable() & iio_triggered_buffer_predisable() in all drivers, since the core handles now the pollfunc attach/detach. The more peculiar change is for the 'at91-sama5d2_adc' driver, since it's not immediately obvious that removing the hooks doesn't break anything. Eugen was able to test on at91-sama5d2-adc driver, sama5d2-xplained board. All seems to be fine.

This will soon change with the upporting of BCM2835 ISP, which make use of the same interface. Break VCHIQ MMAL interface support out from camera host directory to make it possible for the ISP driver to use it as well. The only modification to the existing mmal code is the introduction of EXPORT_SYMBOL() for symbols required by bcm2835-camera and the addition of the module author and licenses.

However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

This makes it more difficult to for example enable triggers via their devm-functions and would need more undo-work in remove. So to make life easier for the driver, move the rest of probe calls also to their devm-equivalents. This includes moving the clk- and regulator-disabling to a devm_action so that they gets disabled both during remove and in the error case in probe, after the action is registered.

This mechanism estimates device internal clock by comparing FIFO interrupts delta time and device elapsed time computed by parsing FIFO data. Take interrupt timestamp in hard irq handler and add IIO device specific timestamp structures in device private allocation.

Until now the driver unified the queue of all interfaces and handled only 4 queues for whole device. This architecture did not allow to balance the traffic between the vif.

Unfortunately, to generate this kind of messages the device squashes all the confirmations whatever their vif ID and use the vif ID of the first confirmation. So, the driver cannot rely on the vif ID mentioned in the header. Fortunately, using the packet_id, the driver can retrieve the Tx request and the associated vif.

So, neither the driver, neither the hardware buffer the frames. So the call to ieee80211_sta_set_buffered is useless. In add, it seems that mac80211 does not expect to receive ieee80211_sta_set_buffered(false) after the station is asleep(). When the device send data to a station, the following sequence can be observed: - Mac80211 call wfx_sta_notify(awake). - The driver calls ieee80211_sta_set_buffered(true). Since the station is awake, its TIM is not set. - Mac80211 receive a power save notification from the station, so it calls wfx_sta_notify(asleep). - Then, since the driver has declared it has buffered some frames, the TIM of the station should be set. This action is delayed by mac80211. - The device also notice the station go to sleep. It replies the REQUEUE status for the buffered frames. The driver forward this status to mac80211. - There is no more frames in queues, so the driver call ieee80211_sta_set_buffered(false). - Mac80211 updates the TIM but since there is no frames buffered by the driver, it set the TIM for the station to 0. Anyway, correctly use the ieee80211_sta_set_buffered() API solves the problem.

However, the device is not able to re-order the frames during BlockAck sessions. Mac80211 is able to reorder the frames, but it need the information about the BlockAck sessions start and stop. Unfortunately, since the BlockAck is fully handled by the hardware, these frames were not forwarded to the host. So, if the driver ask to mac80211 to apply the replay protection, it drop all misordered frames. So, until now, the driver explicitly asked to mac80211 to not apply the CCMP/TKIP replay protection. The situation has changed with the API 3.4 of the device firmware. The firmware forward the BlockAck information. Mac80211 is now able to correctly reorder the frames. There is no more reasons to drop cryptographic data. This patch also impact the older firmwares. There will be a performance impact on these firmware (since the misordered frames will dropped). However, we can't keep the replay protection disabled.

The reason is that we will hide some of the members of the iio_dev structure (to prevent drivers from accessing them directly), and that will also mean hiding the implementation of the iio_priv_to_dev() helper inside the IIO core. Hiding the implementation of iio_priv_to_dev() implies that some fast-paths may not be fast anymore, so a general idea is to try to get rid of the iio_priv_to_dev() altogether. The iio_priv() helper won't be affected by the rework, as the iio_dev struct will keep a reference to the private information. For this driver, not using iio_priv_to_dev(), means reworking some paths to pass the iio device and using iio_priv() to access the private information, and also keeping a reference to the iio device for some quirky paths. One [quirky] path is the at91_adc_workq_handler() which requires the IIO device & the state struct to push to buffers. Since this requires the back-ref to the IIO device, the at91_adc_touch_pos() also uses it. This simplifies the patch a bit. The information required in this function is mostly for debugging purposes. Replacing it with a reference to the IIO device would have been a slightly bigger change, which may not be worth it (for just the debugging purpose and given that we need the back-ref to the IIO device anyway).

Sometimes users copy drivers that are not always the best examples. A better idea is to hide those fields into the framework. For 'struct iio_dev' this is a 'struct iio_dev_opaque' which wraps a public 'struct iio_dev' object. In the next series, some fields will be moved to this new struct, each with it's own rework. This rework will not be complete-able for a while, as many fields need some drivers to be reworked in order to finalize them (e.g. 'indio_dev->mlock'). But some fields can already be moved, and in time, all of them may get there (in the 'struct iio_dev_opaque' object). Since a lot of drivers also call 'iio_priv()', in order to preserve fast-paths (where this matters), the public iio_dev object will have a 'priv' field that will have the pointer to the private information already computed. The reference returned by this field should be guaranteed to be cacheline aligned. The opaque parts will be moved into the 'include/linux/iio/iio-opaque.h' header. Should the hidden information be required for some debugging or some special needs, it can be made available via this header. Otherwise, only the IIO core files should include this file.

By contrast, the GNU General Public -License is intended to guarantee your freedom to share and change free -software--to make sure the software is free for all its users. This -General Public License applies to most of the Free Software -Foundation's software and to any other program whose authors commit to -using it. (Some other Free Software Foundation software is covered by -the GNU Library General Public License instead.) You can apply it to -your programs, too. - - When we speak of free software, we are referring to freedom, not -price. Our General Public Licenses are designed to make sure that you -have the freedom to distribute copies of free software (and charge for -this service if you wish), that you receive source code or can get it -if you want it, that you can change the software or use pieces of it -in new free programs; and that you know you can do these things. - - To protect your rights, we need to make restrictions that forbid -anyone to deny you these rights or to ask you to surrender the rights. -These restrictions translate to certain responsibilities for you if you -distribute copies of the software, or if you modify it. - - For example, if you distribute copies of such a program, whether -gratis or for a fee, you must give the recipients all the rights that -you have. You must make sure that they, too, receive or can get the -source code. And you must show them these terms so they know their -rights. - - We protect your rights with two steps: (1) copyright the software, and -(2) offer you this license which gives you legal permission to copy, -distribute and/or modify the software. - - Also, for each author's protection and ours, we want to make certain -that everyone understands that there is no warranty for this free -software. If the software is modified by someone else and passed on, we -want its recipients to know that what they have is not the original, so -that any problems introduced by others will not reflect on the original -authors' reputations. - - Finally, any free program is threatened constantly by software -patents. We wish to avoid the danger that redistributors of a free -program will individually obtain patent licenses, in effect making the -program proprietary. To prevent this, we have made it clear that any -patent must be licensed for everyone's free use or not licensed at all. - - The precise terms and conditions for copying, distribution and -modification follow. - - GNU GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION - - 0. This License applies to any program or other work which contains -a notice placed by the copyright holder saying it may be distributed -under the terms of this General Public License. The "Program", below, -refers to any such program or work, and a "work based on the Program" -means either the Program or any derivative work under copyright law: -that is to say, a work containing the Program or a portion of it, -either verbatim or with modifications and/or translated into another -language. (Hereinafter, translation is included without limitation in -the term "modification".) Each licensee is addressed as "you". - -Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running the Program is not restricted, and the output from the Program -is covered only if its contents constitute a work based on the -Program (independent of having been made by running the Program). -Whether that is true depends on what the Program does. - - 1. You may copy and distribute verbatim copies of the Program's -source code as you receive it, in any medium, provided that you -conspicuously and appropriately publish on each copy an appropriate -copyright notice and disclaimer of warranty; keep intact all the -notices that refer to this License and to the absence of any warranty; -and give any other recipients of the Program a copy of this License -along with the Program. - -You may charge a fee for the physical act of transferring a copy, and -you may at your option offer warranty protection in exchange for a fee. - - 2. You may modify your copy or copies of the Program or any portion -of it, thus forming a work based on the Program, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) You must cause the modified files to carry prominent notices - stating that you changed the files and the date of any change. - - b) You must cause any work that you distribute or publish, that in - whole or in part contains or is derived from the Program or any - part thereof, to be licensed as a whole at no charge to all third - parties under the terms of this License. - - c) If the modified program normally reads commands interactively - when run, you must cause it, when started running for such - interactive use in the most ordinary way, to print or display an - announcement including an appropriate copyright notice and a - notice that there is no warranty (or else, saying that you provide - a warranty) and that users may redistribute the program under - these conditions, and telling the user how to view a copy of this - License. (Exception: if the Program itself is interactive but - does not normally print such an announcement, your work based on - the Program is not required to print an announcement.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Program, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Program, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Program. - -In addition, mere aggregation of another work not based on the Program -with the Program (or with a work based on the Program) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may copy and distribute the Program (or a work based on it, -under Section 2) in object code or executable form under the terms of -Sections 1 and 2 above provided that you also do one of the following: - - a) Accompany it with the complete corresponding machine-readable - source code, which must be distributed under the terms of Sections - 1 and 2 above on a medium customarily used for software interchange; or, - - b) Accompany it with a written offer, valid for at least three - years, to give any third party, for a charge no more than your - cost of physically performing source distribution, a complete - machine-readable copy of the corresponding source code, to be - distributed under the terms of Sections 1 and 2 above on a medium - customarily used for software interchange; or, - - c) Accompany it with the information you received as to the offer - to distribute corresponding source code. (This alternative is - allowed only for noncommercial distribution and only if you - received the program in object code or executable form with such - an offer, in accord with Subsection b above.) - -The source code for a work means the preferred form of the work for -making modifications to it. For an executable work, complete source -code means all the source code for all modules it contains, plus any -associated interface definition files, plus the scripts used to -control compilation and installation of the executable. However, as a -special exception, the source code distributed need not include -anything that is normally distributed (in either source or binary -form) with the major components (compiler, kernel, and so on) of the -operating system on which the executable runs, unless that component -itself accompanies the executable. - -If distribution of executable or object code is made by offering -access to copy from a designated place, then offering equivalent -access to copy the source code from the same place counts as -distribution of the source code, even though third parties are not -compelled to copy the source along with the object code. - - 4. You may not copy, modify, sublicense, or distribute the Program -except as expressly provided under this License. Any attempt -otherwise to copy, modify, sublicense or distribute the Program is -void, and will automatically terminate your rights under this License. -However, parties who have received copies, or rights, from you under -this License will not have their licenses terminated so long as such -parties remain in full compliance. - - 5. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Program or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Program (or any work based on the -Program), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Program or works based on it. - - 6. Each time you redistribute the Program (or any work based on the -Program), the recipient automatically receives a license from the -original licensor to copy, distribute or modify the Program subject to -these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties to -this License. - - 7. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Program at all. For example, if a patent -license would not permit royalty-free redistribution of the Program by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Program. - -If any portion of this section is held invalid or unenforceable under -any particular circumstance, the balance of the section is intended to -apply and the section as a whole is intended to apply in other -circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system, which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 8. If the distribution and/or use of the Program is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Program under this License -may add an explicit geographical distribution limitation excluding -those countries, so that distribution is permitted only in or among -countries not thus excluded. In such case, this License incorporates -the limitation as if written in the body of this License. - - 9. The Free Software Foundation may publish revised and/or new versions -of the General Public License from time to time. Such new versions will -be similar in spirit to the present version, but may differ in detail to -address new problems or concerns. - -Each version is given a distinguishing version number. If the Program -specifies a version number of this License which applies to it and "any -later version", you have the option of following the terms and conditions -either of that version or of any later version published by the Free -Software Foundation. If the Program does not specify a version number of -this License, you may choose any version ever published by the Free Software -Foundation. - - 10. If you wish to incorporate parts of the Program into other free -programs whose distribution conditions are different, write to the author -to ask for permission. For software which is copyrighted by the Free -Software Foundation, write to the Free Software Foundation; we sometimes -make exceptions for this. Our decision will be guided by the two goals -of preserving the free status of all derivatives of our free software and -of promoting the sharing and reuse of software generally. - - NO WARRANTY - - 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY -FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN -OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES -PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED -OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF -MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS -TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE -PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, -REPAIR OR CORRECTION. - - 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING -WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR -REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, -INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING -OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED -TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY -YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER -PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE -POSSIBILITY OF SUCH DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Programs - - If you develop a new program, and you want it to be of the greatest -possible use to the public, the best way to achieve this is to make it -free software which everyone can redistribute and change under these terms. - - To do so, attach the following notices to the program. It is safest -to attach them to the start of each source file to most effectively -convey the exclusion of warranty; and each file should have at least -the "copyright" line and a pointer to where the full notice is found. - - - Copyright (C) - - This program is free software; you can redistribute it and/or modify - it under the terms of the GNU General Public License as published by - the Free Software Foundation; either version 2 of the License, or - (at your option) any later version. - - This program is distributed in the hope that it will be useful, - but WITHOUT ANY WARRANTY; without even the implied warranty of - MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the - GNU General Public License for more details. - - You should have received a copy of the GNU General Public License - along with this program; if not, write to the Free Software - Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - - -Also add information on how to contact you by electronic and paper mail. - -If the program is interactive, make it output a short notice like this -when it starts in an interactive mode: - - Gnomovision version 69, Copyright (C) year name of author - Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. - This is free software, and you are welcome to redistribute it - under certain conditions; type `show c' for details. - -The hypothetical commands `show w' and `show c' should show the appropriate -parts of the General Public License. Of course, the commands you use may -be called something other than `show w' and `show c'; they could even be -mouse-clicks or menu items--whatever suits your program. - -You should also get your employer (if you work as a programmer) or your -school, if any, to sign a "copyright disclaimer" for the program, if -necessary. Here is a sample; alter the names: - - Yoyodyne, Inc., hereby disclaims all copyright interest in the program - `Gnomovision' (which makes passes at compilers) written by James Hacker. - - , 1 April 1989 - Ty Coon, President of Vice - -This General Public License does not permit incorporating your program into -proprietary programs. If your program is a subroutine library, you may -consider it more useful to permit linking proprietary applications with the -library. If this is what you want to do, use the GNU Library General -Public License instead of this License.

After looking through the discussion logs (on email), it seems that this order was wrong for the start, even though the order implemented in the drivers was correct. Discussions: - first RFC: https://lore.kernel.org/linux-iio/20180622135322.3459-1-alexandru.ardelean@analog.com/ - 2nd patch: https://lore.kernel.org/linux-iio/20181219140912.22582-1-alexandru.ardelean@analog.com/ - final patch-sets: https://lore.kernel.org/linux-iio/20200522104632.517470-1-alexandru.ardelean@analog.com/ https://lore.kernel.org/linux-iio/20200525113855.178821-1-alexandru.ardelean@analog.com/ The last one was applied. The idea is that pollfunc should be attached before calling the 'indio_dev->setup_ops->postenable' hook and should be detached after calling the 'indio_dev->setup_ops->predisable' hook. While the drivers were updated to take this into account, the change to the IIO core was somehow omitted and was made wrong. This change fixes the order to the proper form.

The SADC component in JZ47xx SoCs provides support for touchscreen operations (pen position and pen down pressure) in single-ended and differential modes. The touchscreen component of SADC takes a significant time to stabilize after first receiving the clock and a delay of 50ms has been empirically proven to be a safe value before data sampling can begin. Of the known hardware to use this controller, GCW Zero and Anbernic RG-350 utilize the touchscreen mode by having their joystick(s) attached to the X/Y positive/negative input pins. JZ4770 and later SoCs introduce a low-level command feature. With it, up to 32 commands can be programmed, each one corresponding to a sampling job. It allows to change the low-voltage reference, the high-voltage reference, have them connected to VCC, GND, or one of the X-/X+ or Y-/Y+ pins. This patch introduces support for 6 stream-capable channels: - channel #0 samples X+/GND - channel #1 samples Y+/GND - channel #2 samples X-/GND - channel #3 samples Y-/GND - channel #4 samples X+/X- - channel #5 samples Y+/Y- Being able to sample X-/GND and Y-/GND is useful on some devices, where one joystick is connected to the X+/Y+ pins, and a second joystick is connected to the X-/Y- pins. All the boards which probe this driver have the interrupt provided from Device Tree, with no need to handle a case where the IRQ was not provided.

Two functions of the counter are supported for the moment: period capture and quadrature decoder. The latter is only supported by the SAMA5 series of SoCs. For the period capture mode a basic setup has been chosen that will reset the counter each time the period is actually reached. Of course the device offers much more possibilities. For quadrature mode, both channel 0 and 1 must be configured even if we only capture the position (no revolution/rotation).

Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

They also need to take care of standard configuration registers. Switch to generic power management framework using a single "struct dev_pm_ops" variable to take the unnecessary load from the driver. This also avoids the need for the driver to directly call most of the PCI helper functions and device power state control functions, as through the generic framework PCI Core takes care of the necessary operations, and drivers are required to do only device-specific jobs.

Currently you can't enable the Gey Bus Audio Codec because there is no entry for it in the Kconfig file. Originally the config name was going to be AUDIO_MSM8994 but that's not correct because other types of hardware are supported now. I have chosen the name AUDIO_APB_CODEC instead. Also I had to update the dependencies for GREYBUS_AUDIO to make the compile work.

However ashmem does not support writing into backing shmem with a write syscall. The only way to change its content is to mmap it and operate on mapped memory. Therefore the race that lockdep is warning about is not valid. Resolve this by introducing a separate lockdep class for the backing shmem inodes.
