| 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 |

| 20 | Example: |
| 21 | |
| 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 | }; |
