Merge tag 'pinctrl-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl 

Pull pinctrl changes from Linus Walleij:
 "These are the first and major pinctrl changes for the v3.8 merge
  cycle.  Some of this is used as merge base for other trees so I better
  be early on the trigger.

  As can be seen from the diffstat the major changes are:

  - A big conversion of the AT91 pinctrl driver and the associated ACKed
    platform changes under arch/arm/max-at91 and its device trees.  This
    has been coordinated with the AT91 maintainers to go in through the
    pinctrl tree.

  - A larger chunk of changes to the SPEAr drivers and the addition of
    the "plgpio" driver for the SPEAr as well.

  - The removal of the remnants of the Nomadik driver from the arch/arm
    tree and fusion of that into the Nomadik driver and platform data
    header files.

  - Some local movement in the Marvell MVEBU drivers, these now have
    their own subdirectory.

  - The addition of a chunk of code to gpiolib under drivers/gpio to
    register gpio-to-pin range mappings from the GPIO side of things.
    This has been requested by Grant Likely and is now implemented, it
    is particularly useful for device tree work.

  Then we have incremental updates all over the place, many of these are
  cleanups and fixes from Axel Lin who has done a great job of removing
  minor mistakes and compilation annoyances."

2.1) gpio-controller and pinctrl subsystem
------------------------------------------
gpio-controller on a SOC might be tightly coupled with the pinctrl
subsystem, in the sense that the pins can be used by other functions
together with optional gpio feature.
While the pin allocation is totally managed by the pin ctrl subsystem,
gpio (under gpiolib) is still maintained by gpio drivers. It may happen
that different pin ranges in a SoC is managed by different gpio drivers.
This makes it logical to let gpio drivers announce their pin ranges to
the pin ctrl subsystem and call 'pinctrl_request_gpio' in order to
request the corresponding pin before any gpio usage.
For this, the gpio controller can use a pinctrl phandle and pins to
announce the pinrange to the pin ctrl subsystem. For example,
qe_pio_e: gpio-controller@1460 {
#gpio-cells = <2>;
compatible = "fsl,qe-pario-bank-e", "fsl,qe-pario-bank";
reg = <0x1460 0x18>;
gpio-controller;
gpio-ranges = <&pinctrl1 20 10>, <&pinctrl2 50 20>;
}
where,
&pinctrl1 and &pinctrl2 is the phandle to the pinctrl DT node.
Next values specify the base pin and number of pins for the range
handled by 'qe_pio_e' gpio. In the given example from base pin 20 to
pin 29 under pinctrl1 and pin 50 to pin 69 under pinctrl2 is handled
by this gpio controller.
The pinctrl node must have "#gpio-range-cells" property to show number of
arguments to pass with phandle from gpio controllers node.

* Atmel AT91 Pinmux Controller
The AT91 Pinmux Controler, 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
8 muxing options (called periph modes). Since different modules require
different PAD settings (like pull up, keeper, etc) the contoller controls
also the PAD settings parameters.
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".
Atmel AT91 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, multi drive, etc.
Required properties for iomux controller:
- compatible: "atmel,at91rm9200-pinctrl"
- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
configured in this periph mode. All the periph and bank need to be describe.
How to create such array:
Each column will represent the possible peripheral of the pinctrl
Each line will represent a pio bank
Take an example on the 9260
Peripheral: 2 ( A and B)
Bank: 3 (A, B and C)
=>
/* A B */
0xffffffff 0xffc00c3b /* pioA */
0xffffffff 0x7fff3ccf /* pioB */
0xffffffff 0x007fffff /* pioC */
For each peripheral/bank we will descibe in a u32 if a pin can can be
configured in it by putting 1 to the pin bit (1 << pin)
Let's take the pioA on peripheral B
From the datasheet Table 10-2.

Required properties for pin configuration node:
- atmel,pins: 4 integers array, represents a group of pins mux and config
setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
The PERIPH 0 means gpio.
Bits used for CONFIG:
PULL_UP (1 << 0): indicate this pin need a pull up.
MULTIDRIVE (1 << 1): indicate this pin need to be configured as multidrive.
DEGLITCH (1 << 2): indicate this pin need deglitch.
PULL_DOWN (1 << 3): indicate this pin need a pull down.
DIS_SCHMIT (1 << 4): indicate this pin need to disable schmit trigger.
DEBOUNCE (1 << 16): indicate this pin need debounce.
DEBOUNCE_VAL (0x3fff << 17): debounce val.
NOTE:
Some requirements for using atmel,at91rm9200-pinctrl binding:
1. We have pin function node defined under at91 controller node to represent
what pinmux functions this SoC supports.
2. The driver can use the function node's name and pin configuration node's
name describe the pin function and group hierarchy.
For example, Linux at91 pinctrl driver takes the function node's name
as the function name and pin configuration node's name as group name to
create the map table.
3. Each pin configuration node should have a phandle, devices can set pins
configurations by referring to the phandle of that pin configuration node.
4. The gpio controller must be describe in the pinctrl simple-bus.
Examples:
pinctrl@fffff400 {
#address-cells = <1>;
#size-cells = <1>;
ranges;
compatible = "atmel,at91rm9200-pinctrl", "simple-bus";
reg = <0xfffff400 0x600>;
atmel,mux-mask = <
/* A B */
0xffffffff 0xffc00c3b /* pioA */
0xffffffff 0x7fff3ccf /* pioB */
0xffffffff 0x007fffff /* pioC */
>;
/* shared pinctrl settings */
dbgu {
pinctrl_dbgu: dbgu-0 {
atmel,pins =
<1 14 0x1 0x0 /* PB14 periph A */
1 15 0x1 0x1>; /* PB15 periph with pullup */
};
};
};

reg = <0xfffff200 0x200>;

GPIO controllers and the pinctrl subsystem
------------------------------------------
A GPIO controller on a SOC might be tightly coupled with the pinctrl
subsystem, in the sense that the pins can be used by other functions
together with an optional gpio feature. We have already covered the
case where e.g. a GPIO controller need to reserve a pin or set the
direction of a pin by calling any of:
pinctrl_request_gpio()
pinctrl_free_gpio()
pinctrl_gpio_direction_input()
pinctrl_gpio_direction_output()
But how does the pin control subsystem cross-correlate the GPIO
numbers (which are a global business) to a certain pin on a certain
pin controller?
This is done by registering "ranges" of pins, which are essentially
cross-reference tables. These are described in
Documentation/pinctrl.txt
While the pin allocation is totally managed by the pinctrl subsystem,
gpio (under gpiolib) is still maintained by gpio drivers. It may happen
that different pin ranges in a SoC is managed by different gpio drivers.
This makes it logical to let gpio drivers announce their pin ranges to
the pin ctrl subsystem before it will call 'pinctrl_request_gpio' in order
to request the corresponding pin to be prepared by the pinctrl subsystem
before any gpio usage.
For this, the gpio controller can register its pin range with pinctrl
subsystem. There are two ways of doing it currently: with or without DT.
For with DT support refer to Documentation/devicetree/bindings/gpio/gpio.txt.
For non-DT support, user can call gpiochip_add_pin_range() with appropriate
parameters to register a range of gpio pins with a pinctrl driver. For this
exact name string of pinctrl device has to be passed as one of the
argument to this routine.
What do these conventions omit?
