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; };
