dt-bindings: pinctrl: Convert actions,s700-pinctrl to DT schema

Actions Semi S700 Pin Controller

This binding describes the pin controller found in the S700 SoC.

Required Properties:

- compatible:   Should be "actions,s700-pinctrl"

- reg:          Should contain the register base address and size of

		the pin controller.

- clocks:       phandle of the clock feeding the pin controller

- gpio-controller: Marks the device node as a GPIO controller.

- gpio-ranges: Specifies the mapping between gpio controller and

               pin-controller pins.

- #gpio-cells: Should be two. The first cell is the gpio pin number

		and the second cell is used for optional parameters.

- interrupt-controller: Marks the device node as an interrupt controller.

- #interrupt-cells: Specifies the number of cells needed to encode an

		interrupt.  Shall be set to 2.  The first cell

		defines the interrupt number, the second encodes

		the trigger flags described in

		bindings/interrupt-controller/interrupts.txt

- interrupts: The interrupt outputs from the controller. There is one GPIO

              interrupt per GPIO bank. The number of interrupts listed depends

              on the number of GPIO banks on the SoC. The interrupts must be

              ordered by bank, starting with bank 0.

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 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 group(s), and various pin configuration

parameters, such as pull-up, drive strength, etc.

PIN CONFIGURATION NODES:

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.

Pinmux functions are available only for the pin groups while pinconf

parameters are available for both pin groups and individual pins.

The following generic properties as defined in pinctrl-bindings.txt are valid

to specify in a pin configuration subnode:
