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 | |
