Merge branch 'spear-for-3.8' of git://git.linaro.org/people/vireshk/linux into next/dt2

From Viresh Kumar <viresh.kumar@linaro.org>:

These are DT updates for SPEAr SoCs. There aren't any fixes that we want
to get into 3.7-rc* and we are happy with 3.8.

Some of the dtbs which use gpiopinctrl have dependency on Linus's
pinctrl tree, where an earlier update for adding gpiopinctrl node is present.

* SPEAr Shared IRQ layer (shirq)
SPEAr3xx architecture includes shared/multiplexed irqs for certain set
of devices. The multiplexor provides a single interrupt to parent
interrupt controller (VIC) on behalf of a group of devices.
There can be multiple groups available on SPEAr3xx variants but not
exceeding 4. The number of devices in a group can differ, further they
may share same set of status/mask registers spanning across different
bit masks. Also in some cases the group may not have enable or other
registers. This makes software little complex.
A single node in the device tree is used to describe the shared
interrupt multiplexor (one node for all groups). A group in the
interrupt controller shares config/control registers with other groups.
For example, a 32-bit interrupt enable/disable config register can
accommodate upto 4 interrupt groups.
Required properties:
- compatible: should be, either of
- "st,spear300-shirq"
- "st,spear310-shirq"
- "st,spear320-shirq"
- interrupt-controller: Identifies the node as an interrupt controller.
- #interrupt-cells: should be <1> which basically contains the offset
(starting from 0) of interrupts for all the groups.
- reg: Base address and size of shirq registers.
- interrupts: The list of interrupts generated by the groups which are
then connected to a parent interrupt controller. Each group is
associated with one of the interrupts, hence number of interrupts (to
parent) is equal to number of groups. The format of the interrupt
specifier depends in the interrupt parent controller.
Optional properties:
- interrupt-parent: pHandle of the parent interrupt controller, if not
inherited from the parent node.
Example:
The following is an example from the SPEAr320 SoC dtsi file.
shirq: interrupt-controller@0xb3000000 {
compatible = "st,spear320-shirq";
reg = <0xb3000000 0x1000>;
interrupts = <28 29 30 1>;

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.
=== ST Microelectronics SPEAr SPI CS Driver ===
SPEAr platform provides a provision to control chipselects of ARM PL022 Prime
Cell spi controller through its system registers, which otherwise remains under
PL022 control. If chipselect remain under PL022 control then they would be
released as soon as transfer is over and TxFIFO becomes empty. This is not
desired by some of the device protocols above spi which expect (multiple)
transfers without releasing their chipselects.
Chipselects can be controlled by software by turning them as GPIOs. SPEAr
provides another interface through system registers through which software can
directly control each PL022 chipselect. Hence, it is natural for SPEAr to export
the control of this interface as gpio.
Required properties:
* compatible: should be defined as "st,spear-spics-gpio"
* reg: mentioning address range of spics controller
* st-spics,peripcfg-reg: peripheral configuration register offset
* st-spics,sw-enable-bit: bit offset to enable sw control
* st-spics,cs-value-bit: bit offset to drive chipselect low or high
* st-spics,cs-enable-mask: chip select number bit mask
* st-spics,cs-enable-shift: chip select number program offset
* gpio-controller: Marks the device node as gpio controller
* #gpio-cells: should be 1 and will mention chip select number
All the above bit offsets are within peripcfg register.
Example:
-------
spics: spics@e0700000{
compatible = "st,spear-spics-gpio";
reg = <0xe0700000 0x1000>;

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.
