1 Ingenic jz47xx GPIO controller
3 That the Ingenic GPIO driver node must be a sub-node of the Ingenic pinctrl
9 - compatible: Must contain one of:
10 - "ingenic,jz4740-gpio"
11 - "ingenic,jz4770-gpio"
12 - "ingenic,jz4780-gpio"
13 - reg: The GPIO bank number.
14 - interrupt-controller: Marks the device node as an interrupt controller.
15 - interrupts: Interrupt specifier for the controllers interrupt.
16 - #interrupt-cells: Should be 2. Refer to
17 ../interrupt-controller/interrupts.txt for more details.
18 - gpio-controller: Marks the device node as a GPIO controller.
19 - #gpio-cells: Should be 2. The first cell is the GPIO number and the second
20 cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>. Only the
21 GPIO_ACTIVE_HIGH and GPIO_ACTIVE_LOW flags are supported.
22 - gpio-ranges: Range of pins managed by the GPIO controller. Refer to
23 'gpio.txt' in this directory for more details.
