Subject: [PATCH] dt-bindings: pinctrl: Convert actions,s700-pinctrl to DT schema
Convert the actions,s700-pinctrl binding to DT schema format. It's a
straight-forward conversion.

-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:
-
-Required Properties:
-
