1 Every GPIO controller node must have #gpio-cells property defined,
2 this information will be used to translate gpio-specifiers.
13 - #gpio-cells : Should be two. The first cell is the pin number and the
15 - gpio-controller : Marks the port as GPIO controller.
17 Example of three SOC GPIO banks defined as gpio-controller nodes:
19 	CPM1_PIO_A: gpio-controller@950 {
20 		#gpio-cells = <2>;
23 		gpio-controller;
26 	CPM1_PIO_B: gpio-controller@ab8 {
27 		#gpio-cells = <2>;
30 		gpio-controller;
33 	CPM1_PIO_E: gpio-controller@ac8 {
34 		#gpio-cells = <2>;
37 		gpio-controller;
