* Abilis TB10x GPIO controller Required Properties: - compatible: Should be "abilis,tb10x-gpio" - reg: Address and length of the register set for the device - gpio-controller: Marks the device node as a gpio controller. - #gpio-cells: Should be <2>. 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). - abilis,ngpio: the number of GPIO pins this driver controls. Optional Properties: - interrupt-controller: Marks the device node as an interrupt controller. - #interrupt-cells: Should be <1>. Interrupts are triggered on both edges. - interrupts: Defines the interrupt line connecting this GPIO controller to its parent interrupt controller. GPIO ranges are specified as described in Documentation/devicetree/bindings/gpio/gpio.txt Example: gpioa: gpio@ff140000 { compatible = "abilis,tb10x-gpio"; interrupt-controller; #interrupt-cells = <1>; interrupt-parent = <&tb10x_ictl>; interrupts = <27 2>; reg = <0xFF140000 0x1000>; gpio-controller; #gpio-cells = <2>; abilis,ngpio = <3>; gpio-ranges = <&iomux 0 0 0>; gpio-ranges-group-names = "gpioa_pins"; };
