1 * Marvell PXA GPIO controller
4 - compatible : Should be "mrvl,pxa-gpio" or "mrvl,mmp-gpio"
5 - reg : Address and length of the register set for the device
6 - interrupts : Should be the port interrupt shared by all gpio pins.
7 There're three gpio interrupts in arch-pxa, and they're gpio0,
8 gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
10 - interrupt-name : Should be the name of irq resource. Each interrupt
11 binds its interrupt-name.
12 - interrupt-controller : Identifies the node as an interrupt controller.
13 - #interrupt-cells: Specifies the number of cells needed to encode an
15 - gpio-controller : Marks the device node as a gpio controller.
16 - #gpio-cells : Should be one. It is the pin number.
