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

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 };
