1	twl4030 GPIO controller bindings
2	
3	Required properties:
4	- compatible:
5	  - "ti,twl4030-gpio" for twl4030 GPIO controller
6	- #gpio-cells : Should be two.
7	  - first cell is the pin number
8	  - second cell is used to specify optional parameters (unused)
9	- gpio-controller : Marks the device node as a GPIO controller.
10	- #interrupt-cells : Should be 2.
11	- interrupt-controller: Mark the device node as an interrupt controller
12	  The first cell is the GPIO number.
13	  The second cell is not used.
14	- ti,use-leds : Enables LEDA and LEDB outputs if set
15	- ti,debounce : if n-th bit is set, debounces GPIO-n
16	- ti,mmc-cd : if n-th bit is set, GPIO-n controls VMMC(n+1)
17	- ti,pullups : if n-th bit is set, set a pullup on GPIO-n
18	- ti,pulldowns : if n-th bit is set, set a pulldown on GPIO-n
19	
20	Example:
21	
22	twl_gpio: gpio {
23	    compatible = "ti,twl4030-gpio";
24	    #gpio-cells = <2>;
25	    gpio-controller;
26	    #interrupt-cells = <2>;
27	    interrupt-controller;
28	    ti,use-leds;
29	};
