38d324df75 mmc: rtsx: Configure SD_CFG2 register in sd_rw_multi
For Realtek card reader, internal regsiter SD_CFG2 should be configured
before transferring data.
The default value of SD_CFG2 is proper for writing data. But for reading
sequence, the timing is not good enough. So in some extreme circumstance,
card reader may sample the response data from the card as good even if
the data is wrong. And this will cause the bad consequence.
In the prior version, the value of this register has been calculated,
but forgotten to write back to the internal register.

1950c71646 mfd: sta2x11-mfd: Add apb-soc regs driver and factor out common code
A driver for the apb-soc registers is needed by the clock
infrastructure code to configure and control clocks on the sta2x11
chip.

Since some of the functions in sta2x11-mfd.c were almost identical
for the two existing platform devices, the following changes
have been performed to avoid further code duplication while
adding the apb-soc-regs driver:

* The sctl_regs and apbreg_regs fields in struct sta2x11_mfd
have been turned into just one array of pointers accessed by
device index.
* Platform probe methods have become one-liners invoking a
common probe with the device's index as second parameter.
* For loops have been inserted where the same operations
were performed for each of the two bars of a pci device.
* The apbreg_mask and sctl_mask functions were almost identical,
so they were turned into inline functions invoking a common
__sta2x11_mfd_mask() with the platform device's index as last
parameter. To do this, enum sta2x11_mfd_plat_dev has been declared in
sta2x11-mfd.h and more device types have been added to it.

b9fbb62eb6 mfd: Only unregister platform devices allocated by the mfd core
mfd_remove_devices would iterate over all devices sharing a parent with
an mfd device regardless of whether they were allocated by the mfd core
or not. This especially caused problems when the device structure was
not contained within a platform_device, because to_platform_device is
used on each device pointer.

This patch defines a device_type for mfd devices and checks this is
present from mfd_remove_devices_fn before processing the device.

ffe20b6854 mfd: da9052-core: Use regmap_irq_get_virq() and fix the probe
On a mx53qsb dt-kernel the da9052-core driver fails to probe as follows:

da9052 1-0048: DA9052 ADC IRQ failed ret=-22

The reason for the error was due to passing only the offset as the interrupt
number in request_threaded_irq() without da9052->irq_base.

The recommended approach though is to use regmap_get_virq() to acquire the
interrupt number and this allows to get rid of da9052->irq_base.

Fix it and allow the driver to probe successfully.

Also provide a few more error logs and change the irq string to "adc-irq", so
that it appears as a single word in 'cat /proc/interrupts'

90a38d9997 mfd: Remove Unicode Byte Order Marks from da9055
Older gcc (< 4.4) doesn't like files starting with Unicode BOMs:

include/linux/mfd/da9055/core.h:1: error: stray ‘\357’ in program
include/linux/mfd/da9055/core.h:1: error: stray ‘\273’ in program
include/linux/mfd/da9055/core.h:1: error: stray ‘\277’ in program
include/linux/mfd/da9055/pdata.h:1: error: stray ‘\357’ in program
include/linux/mfd/da9055/pdata.h:1: error: stray ‘\273’ in program
include/linux/mfd/da9055/pdata.h:1: error: stray ‘\277’ in program
include/linux/mfd/da9055/reg.h:1: error: stray ‘\357’ in program
include/linux/mfd/da9055/reg.h:1: error: stray ‘\273’ in program
include/linux/mfd/da9055/reg.h:1: error: stray ‘\277’ in program

Remove the BOMs, the rest of the files is plain ASCII anyway.

Output of "file" before:

include/linux/mfd/da9055/core.h:  UTF-8 Unicode (with BOM) C program text
include/linux/mfd/da9055/pdata.h: UTF-8 Unicode (with BOM) C program text
include/linux/mfd/da9055/reg.h:   UTF-8 Unicode (with BOM) C program text

Output of "file" after:

include/linux/mfd/da9055/core.h:  ASCII C program text
include/linux/mfd/da9055/pdata.h: ASCII C program text
include/linux/mfd/da9055/reg.h:   ASCII C program text

b851c06c24 mfd: Differentiate between u8500 and u9540 TCDM address mapping
The TCDM mappings are quite different from u8500 to u9540. If these
aren't correctly specified for a given board, it will fail to boot.
Here we add the correct TCDM base for the u9540.

Please note that although this patch allows us to boot the u9540,
it doesn't provide us with full enablement. For that, another
patch-set will follow which completely re-vamps the way the PRCMU
is passed TCDM mappings.

8c4203cb58 mfd: ab8500-core: Use devm_* memory/IRQ and allocation/free routines
It is better to use devm_* calls, as they allow for easier
and more automatic clean-up. Resources are device allocated,
so when a device is freed, so are all associated resources.
