@ -8,6 +8,17 @@ Required Properties:
- 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
