1* Freescale MPC512x/MPC8xxx/QorIQ/Layerscape GPIO controller
2
3Required properties:
4- compatible : Should be "fsl,<soc>-gpio"
5  The following <soc>s are known to be supported:
6	mpc5121, mpc5125, mpc8349, mpc8572, mpc8610, pq3, qoriq,
7	ls1021a, ls1043a, ls2080a.
8- reg : Address and length of the register set for the device
9- interrupts : Should be the port interrupt shared by all 32 pins.
10- #gpio-cells : Should be two.  The first cell is the pin number and
11  the second cell is used to specify the gpio polarity:
12      0 = active high
13      1 = active low
14
15Optional properties:
16- little-endian : GPIO registers are used as little endian. If not
17                  present registers are used as big endian by default.

19Example of gpio-controller node for a mpc5125 SoC:
20
21gpio0: gpio@1100 {
22	compatible = "fsl,mpc5125-gpio";
23	#gpio-cells = <2>;
24	reg = <0x1100 0x080>;
25	interrupts = <78 0x8>;
26};
27
28Example of gpio-controller node for a ls2080a SoC:
29
30gpio0: gpio@2300000 {
31	compatible = "fsl,ls2080a-gpio", "fsl,qoriq-gpio";
32	reg = <0x0 0x2300000 0x0 0x10000>;
33	interrupts = <0 36 0x4>; /* Level high type */
34	gpio-controller;
35	little-endian;
36	#gpio-cells = <2>;
37	interrupt-controller;
38	#interrupt-cells = <2>;
39};
