dt-bindings: gpio: Convert Arm PL061 to json-schema
Convert the Arm PL061 GPIO controller binding to json-schema format. As I'm the author for all but the gpio-ranges line, make the schema dual GPL/BSD license.

ARM PL061 GPIO controller
|
|
||||||
|
|
||||||
Required properties:
|
|
||||||
- compatible : "arm,pl061", "arm,primecell"
|
|
||||||
- #gpio-cells : Should be two. The first cell is the pin number and the
|
|
||||||
second cell is used to specify optional parameters:
|
|
||||||
- bit 0 specifies polarity (0 for normal, 1 for inverted)
|
|
||||||
- gpio-controller : Marks the device node as a GPIO controller.
|
|
||||||
- interrupts : Interrupt mapping for GPIO IRQ.
|
|
||||||
- gpio-ranges : Interaction with the PINCTRL subsystem.
