Pin control changes for the v3.11 kernel cycle:
- A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090. Support BIAS_BUS_HOLD, get device tree parsing and debugfs support into shape. - We also have device tree support with generic naming conventions for the generic pin configuration. - Delete the unused and confusing direct pinconf API. Now state transitions is *the* way to control pins and multiplexing. - New drivers for Rockchip, TZ1090, and TZ1090 PDC. - Two pin control states related to power management are now handled in the device core: "sleep" and "idle", removing a lot of boilerplate code in drivers. We do not yet know if this is the final word for pin PM, but it already make things a lot easier to handle. - Handle sparse GPIO ranges passing a list of disparate pins, and utilize these in the new BayTrail (x86 Atom SoC) driver. - Make the sunxi (AllWinner) driver handle external interrupts. - Make it possible for pinctrl-single to handle the case where several pins are managed by a single register, and augment it to handle sleep modes. - Cleanups and improvements for the abx500 drivers. - Move Sirf pin control drivers to their own directory, support save/restore of context and add support for the SiRFatlas6 SoC. - PMU muxing for the Dove pinctrl driver. - Finalization and support for VF610 in the i.MX6 pinctrl driver. - Smoothen out various Exynos rough edges. - Generic cleanups of various kinds. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAABAgAGBQJR0Z07AAoJEEEQszewGV1zx+oP/j+bh39e1Fc8ySFNvpwLFFRb EbQZx21XsK+d4fUVYQJ1IBh3e5FTqkmvHarbO1aNttqyk7eN5P4EFb3dLExIX+81 6SJYtldH5ZdvLpJNvSXAX6fUjTD1CtBCDs5z5AvDQjqUArQ2tKlzJJgFXW8MSd3B 5hd7XdU5g30GbVzFwrPbVUZwRM12YVs/HACkP6uFqDjB8KX6nXpETlqeeFW+ApvW RPT7iN/CsFls7gl6mHsPvScdfXar0ilZfu0hTf3EmhlVK1/iPOV6aqAF9z4j2Yxf ICL/x3phJ0Q7yNeZslif0KN3iJnrRGbdNvBi6wim35Ds5Uf3lY2SAhSvxNmkjT8n DB9oBTvQzr5OEv8fstWJAT+BWIdZ6Z91IqJ5Gy40A91oVUU9NDDBR3ur2gIneEUz 51kOUhucCzpiht5A/7djAx6MYYOEUwjGNzjOs7tGcxCxz4+Rb2DbAXZ3Cew45ddh 1QsfL3588A0DTp7ccw7f4QwYveX/cquzia/MD8AtdrUSYFEPfkexEo540/VqMl8j aMJ8Uuca9GSnyXDk+ziwkzLg2DjTw+p+6IygNr2GLrXFH2LTAKRpz/SidyLArDsw 0sTFan0sdU3497rHX5Xc8yCyDY4sXCdQm3/er+TE+Z7V2dS99GuEysCAInIdvM1I Wupqaxw4A25YSmbRFVpR =EbAf -----END PGP SIGNATURE----- Merge tag 'pinctrl-for-v3.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl Pull pin control changes from Linus Walleij: - A large slew of improvements of the Genric pin configuration support, and deployment in four different platforms: Rockchip, Super-H PFC, ABx500 and TZ1090.

ImgTec TZ1090 PDC pin controller
|
||||
|
||||
Required properties:
|
||||
- compatible: "img,tz1090-pdc-pinctrl"
|
||||
- reg: Should contain the register physical address and length of the
|
||||
SOC_GPIO_CONTROL registers in the PDC register region.
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
TZ1090-PDC's pin configuration nodes act as a container for an abitrary number
|
||||
of subnodes. Each of these subnodes represents some desired configuration for a
|
||||
pin, a group, or a list of pins or groups. This configuration can include the
|
||||
mux function to select on those pin(s)/group(s), and various pin configuration
|
||||
parameters, such as pull-up, drive strength, etc.
|
||||
|
||||
The name of each subnode is not important; all subnodes should be enumerated
|
||||
and processed purely based on their content.
|
||||
|
||||
Each subnode only affects those parameters that are explicitly listed. In
|
||||
other words, a subnode that lists a mux function but no pin configuration
|
||||
parameters implies no information about any pin configuration parameters.
|
||||
Similarly, a pin subnode that describes a pullup parameter implies no
|
||||
information about e.g. the mux function. For this reason, even seemingly boolean
|
||||
values are actually tristates in this binding: unspecified, off, or on.
|
||||
Unspecified is represented as an absent property, and off/on are represented as
|
||||
integer values 0 and 1.
|
||||
|
||||
Required subnode-properties:
|
||||
- tz1090,pins : An array of strings. Each string contains the name of a pin or
|
||||
group. Valid values for these names are listed below.
|
||||
|
||||
Optional subnode-properties:
|
||||
- tz1090,function: A string containing the name of the function to mux to the
|
||||
pin or group. Valid values for function names are listed below, including
|
||||
which pingroups can be muxed to them.
|
||||
- supported generic pinconfig properties (for further details see
|
||||
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt):
|
||||
- bias-disable
|
||||
- bias-high-impedance
|

- bias-bus-hold
|
||||
- bias-pull-up
|
||||
- bias-pull-down
|
||||
- input-schmitt-enable
|

- input-schmitt-disable
|
||||
- drive-strength: Integer, control drive strength of pins in mA.
|
||||
2: 2mA
|
||||
4: 4mA
|
||||
8: 8mA
|
||||
12: 12mA
|
||||
- low-power-enable: Flag, power-on-start weak pull-down for invalid power.
|
||||
- low-power-disable: Flag, power-on-start weak pull-down disabled.
|
||||
|
||||
Note that many of these properties are only valid for certain specific pins
|
||||
or groups. See the TZ1090 TRM for complete details regarding which groups
|
||||
support which functionality. The Linux pinctrl driver may also be a useful
|
||||
reference.
|
||||
|
||||
Valid values for pin and group names are:
|
||||
|
||||
pins:
|
||||
|
||||
These all support bias-high-impediance, bias-pull-up, bias-pull-down, and
|
||||
bias-bus-hold (which can also be provided to any of the groups below to set
|
||||
it for all gpio pins in that group).
|
||||
|
||||
gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data, ext_power.
|
||||
|
||||
mux groups:
|
||||
|
||||
These all support function.
|
||||
|
||||
gpio0
|
||||
pins: gpio0.
|
||||
function: ir_mod_stable_out.
|
||||
gpio1
|
||||
pins: gpio1.
|
||||
function: ir_mod_power_out.
|
||||
|
||||
drive groups:
|
||||
|

These support input-schmitt-enable, input-schmitt-disable,
|
||||
drive-strength, low-power-enable, and low-power-disable.
|

pdc
|
||||
pins: gpio0, gpio1, sys_wake0, sys_wake1, sys_wake2, ir_data,

|
||||
|

Valid values for pin and group names are:
|
||||
|
||||
gpio pins:
|
||||
|
||||
These all support bias-high-impediance, bias-pull-up, bias-pull-down, and
|
||||
bias-bus-hold (which can also be provided to any of the groups below to set
|
||||
it for all pins in that group).
|
||||
|
||||
They also all support the some form of muxing. Any pins which are contained
|
||||
in one of the mux groups (see below) can be muxed only to the functions
|
||||
supported by the mux group. All other pins can be muxed to the "perip"
|
||||
function which which enables them with their intended peripheral.
|
||||
|
||||
Different pins in the same mux group cannot be muxed to different functions,
|
||||
however it is possible to mux only a subset of the pins in a mux group to a
|
||||
particular function and leave the remaining pins unmuxed. This is useful if
|
||||
the board connects certain pins in a group to other devices to be controlled
|
||||
by GPIO, and you don't want the usual peripheral to have any control of the
|
||||
pin.

* Renesas Pin Function Controller (GPIO and Pin Mux/Config)
|
||||
|
||||
The Pin Function Controller (PFC) is a Pin Mux/Config controller. On SH7372,
|
||||
SH73A0, R8A73A4 and R8A7740 it also acts as a GPIO controller.
|
||||
|
||||
|
||||
Pin Control
|
||||
-----------
|
||||
|
||||
Required Properties:
|
||||
|
||||
- compatible: should be one of the following.
|
||||
- "renesas,pfc-r8a73a4": for R8A73A4 (R-Mobile APE6) compatible pin-controller.
|
||||
- "renesas,pfc-r8a7740": for R8A7740 (R-Mobile A1) compatible pin-controller.
|
||||
- "renesas,pfc-r8a7778": for R8A7778 (R-Mobile M1) compatible pin-controller.
|
||||
- "renesas,pfc-r8a7779": for R8A7779 (R-Car H1) compatible pin-controller.
|
||||
- "renesas,pfc-r8a7790": for R8A7790 (R-Car H2) compatible pin-controller.
|
||||
- "renesas,pfc-sh7372": for SH7372 (SH-Mobile AP4) compatible pin-controller.
|
||||
- "renesas,pfc-sh73a0": for SH73A0 (SH-Mobile AG5) compatible pin-controller.
|
||||
|
||||
- reg: Base address and length of each memory resource used by the pin
|
||||
controller hardware module.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- #gpio-range-cells: Mandatory when the PFC doesn't handle GPIO, forbidden
|
||||
otherwise. Should be 3.
|
||||
|
||||
The PFC node also acts as a container for pin configuration nodes. Please refer
|
||||
to pinctrl-bindings.txt in this directory for the definition of the term "pin
|
||||
configuration node" and for the common pinctrl bindings used by client devices.
|
||||
|
||||
Each pin configuration node represents a desired configuration for a pin, a
|
||||
pin group, or a list of pins or pin groups. The configuration can include the
|
||||
function to select on those pin(s) and pin configuration parameters (such as
|
||||
pull-up and pull-down).
|
||||
|
||||
Pin configuration nodes contain pin configuration properties, either directly
|
||||
or grouped in child subnodes. Both pin muxing and configuration parameters can
|
||||
be grouped in that way and referenced as a single pin configuration node by
|
||||
client devices.
|
||||
|
||||
A configuration node or subnode must reference at least one pin (through the
|
||||
pins or pin groups properties) and contain at least a function or one
|
||||
configuration parameter. When the function is present only pin groups can be
|
||||
used to reference pins.
|
||||
|
||||
All pin configuration nodes and subnodes names are ignored. All of those nodes
|
||||
are parsed through phandles and processed purely based on their content.
|
||||
|
||||
Pin Configuration Node Properties:
|
||||
|
||||
- renesas,pins : An array of strings, each string containing the name of a pin.
|
||||
- renesas,groups : An array of strings, each string containing the name of a pin
|
||||
group.
|
||||
|
||||
- renesas,function: A string containing the name of the function to mux to the
|
||||
pin group(s) specified by the renesas,groups property
|
||||
|
||||
Valid values for pin, group and function names can be found in the group and
|
||||
function arrays of the PFC data file corresponding to the SoC
|
||||
(drivers/pinctrl/sh-pfc/pfc-*.c)
|
||||
|
||||
The pin configuration parameters use the generic pinconf bindings defined in
|
||||
pinctrl-bindings.txt in this directory. The supported parameters are
|
||||
bias-disable, bias-pull-up and bias-pull-down.
|
||||
|
||||
|
||||
GPIO
|
||||
----
|
||||
|
||||
On SH7372, SH73A0, R8A73A4 and R8A7740 the PFC node is also a GPIO controller
|
||||
node.
|
||||
|
||||
Required Properties:
|
||||
|
||||
- gpio-controller: Marks the device node as a gpio controller.
|
||||
|
||||
- #gpio-cells: Should be 2. The first cell is the GPIO number and the second
|
||||
cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
|
||||
GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
|
||||
|
||||
The syntax of the gpio specifier used by client nodes should be the following
|
||||
with values derived from the SoC user manual.
|
||||
|
||||
<[phandle of the gpio controller node]
|
||||
[pin number within the gpio controller]
|
||||
[flags]>
|
||||
|
||||
On other mach-shmobile platforms GPIO is handled by the gpio-rcar driver.
|
||||
Please refer to Documentation/devicetree/bindings/gpio/renesas,gpio-rcar.txt
|
||||
for documentation of the GPIO device tree bindings on those platforms.

* Rockchip Pinmux Controller
|
||||
|
||||
The Rockchip Pinmux Controller, enables the IC
|
||||
to share one PAD to several functional blocks. The sharing is done by
|
||||
multiplexing the PAD input/output signals. For each PAD there are up to
|
||||
4 muxing options with option 0 being the use as a GPIO.
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
The Rockchip pin configuration node is a node of a group of pins which can be
|
||||
used for a specific device or function. This node represents both mux and
|
||||
config of the pins in that group. The 'pins' selects the function mode(also
|
||||
named pin mode) this pin can work on and the 'config' configures various pad
|
||||
settings such as pull-up, etc.
|
||||
|
||||
The pins are grouped into up to 5 individual pin banks which need to be
|
||||
defined as gpio sub-nodes of the pinmux controller.
|
||||
|
||||
Required properties for iomux controller:
|
||||
- compatible: one of "rockchip,rk2928-pinctrl", "rockchip,rk3066a-pinctrl"
|
||||
"rockchip,rk3066b-pinctrl", "rockchip,rk3188-pinctrl"
|
||||
|
||||
Required properties for gpio sub nodes:
|
||||
- compatible: "rockchip,gpio-bank"
|
||||
- reg: register of the gpio bank (different than the iomux registerset)
|
||||
- interrupts: base interrupt of the gpio bank in the interrupt controller
|
||||
- clocks: clock that drives this bank
|
||||
- gpio-controller: identifies the node as a gpio controller and pin bank.
|
||||
- #gpio-cells: number of cells in GPIO specifier. Since the generic GPIO
|
||||
binding is used, the amount of cells must be specified as 2. See generic
|
||||
GPIO binding documentation for description of particular cells.
|
||||
- interrupt-controller: identifies the controller node as interrupt-parent.
|
||||
- #interrupt-cells: the value of this property should be 2 and the interrupt
|
||||
cells should use the standard two-cell scheme described in
|
||||
bindings/interrupt-controller/interrupts.txt
|
||||
|
||||
Required properties for pin configuration node:
|
||||
- rockchip,pins: 3 integers array, represents a group of pins mux and config
|
||||
setting. The format is rockchip,pins = <PIN_BANK PIN_BANK_IDX MUX &phandle>.
|
||||
The MUX 0 means gpio and MUX 1 to 3 mean the specific device function.
|
||||
The phandle of a node containing the generic pinconfig options
|
||||
to use, as described in pinctrl-bindings.txt in this directory.
|
||||

ST Ericsson abx500 pinmux controller
|
||||
|
||||
Required properties:
|
||||
- compatible: "stericsson,ab8500-gpio", "stericsson,ab8540-gpio",
|
||||
"stericsson,ab8505-gpio", "stericsson,ab9540-gpio",
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
|
||||
subnodes. Each of these subnodes represents some desired configuration for a
|
||||
pin, a group, or a list of pins or groups. This configuration can include the
|
||||
mux function to select on those pin(s)/group(s), and various pin configuration
|
||||
parameters, such as input, output, pull up, pull down...
|
||||
|
||||
The name of each subnode is not important; all subnodes should be enumerated
|
||||
and processed purely based on their content.
|
||||
|
||||
Required subnode-properties:
|
||||
- ste,pins : An array of strings. Each string contains the name of a pin or
|
||||
group.
|
||||
|
||||
Optional subnode-properties:
|
||||
- ste,function: A string containing the name of the function to mux to the
|
||||
pin or group.
|
||||
|
||||
- generic pin configuration option to use. Example :
|
||||
|
||||
default_cfg {
|
||||
ste,pins = "GPIO1";
|
||||
bias-disable;
|
||||
};
|
||||
|
||||
- ste,config: Handle of pin configuration node containing the generic
|
||||
pinconfig options to use, as described in pinctrl-bindings.txt in
|
||||
this directory. Example :
|
||||
|
||||
pcfg_bias_disable: pcfg_bias_disable {
|
||||
bias-disable;
|
||||
};
|
||||
|
||||
default_cfg {
|
||||
ste,pins = "GPIO1";

ste.config = <&pcfg_bias_disable>;
