1twl4030 GPIO controller bindings
2
3Required 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
