-twl4030 GPIO controller bindings
-
-Required properties:
-- compatible:
- - "ti,twl4030-gpio" for twl4030 GPIO controller
-- #gpio-cells : Should be two.
- - first cell is the pin number
- - second cell is used to specify optional parameters (unused)
-- gpio-controller : Marks the device node as a GPIO controller.
-- #interrupt-cells : Should be 2.
-- interrupt-controller: Mark the device node as an interrupt controller
- The first cell is the GPIO number.
- The second cell is not used.
-- ti,use-leds : Enables LEDA and LEDB outputs if set
-- ti,debounce : if n-th bit is set, debounces GPIO-n
-- ti,mmc-cd : if n-th bit is set, GPIO-n controls VMMC(n+1)
-- ti,pullups : if n-th bit is set, set a pullup on GPIO-n
-- ti,pulldowns : if n-th bit is set, set a pulldown on GPIO-n

-Example:
-
-twl_gpio: gpio {
- compatible = "ti,twl4030-gpio";
- #gpio-cells = <2>;
- gpio-controller;
- #interrupt-cells = <2>;
- interrupt-controller;
- ti,use-leds;
-};
