1 * Marvell PXA GPIO controller
4 - compatible : Should be "intel,pxa25x-gpio", "intel,pxa26x-gpio",
5 "intel,pxa27x-gpio", "intel,pxa3xx-gpio",
6 "marvell,pxa93x-gpio", "marvell,mmp-gpio" or
8 - reg : Address and length of the register set for the device
9 - interrupts : Should be the port interrupt shared by all gpio pins.
10 There're three gpio interrupts in arch-pxa, and they're gpio0,
11 gpio1 and gpio_mux. There're only one gpio interrupt in arch-mmp,
13 - interrupt-name : Should be the name of irq resource. Each interrupt
14 binds its interrupt-name.
15 - interrupt-controller : Identifies the node as an interrupt controller.
16 - #interrupt-cells: Specifies the number of cells needed to encode an
18 - gpio-controller : Marks the device node as a gpio controller.
19 - #gpio-cells : Should be one. It is the pin number.
24 compatible = "marvell,mmp-gpio";
25 reg = <0xd4019000 0x1000>;
27 interrupt-name = "gpio_mux";
31 #interrupt-cells = <1>;
34 * Marvell Orion GPIO Controller
37 - compatible : Should be "marvell,orion-gpio"
38 - reg : Address and length of the register set for controller.
39 - gpio-controller : So we know this is a gpio controller.
40 - ngpio : How many gpios this controller has.
41 - interrupts : Up to 4 Interrupts for the controller.
44 - mask-offset : For SMP Orions, offset for Nth CPU
49 compatible = "marvell,orion-gpio";
54 interrupts = <35>, <36>, <37>, <38>;
