| LEDs connected to tca6507 |
| |
| Required properties: |
| - compatible : should be : "ti,tca6507". |
| - #address-cells: must be 1 |
| - #size-cells: must be 0 |
| - reg: typically 0x45. |
| |
| Optional properties: |
| - gpio-controller: allows lines to be used as output-only GPIOs. |
| - #gpio-cells: if present, must be 0. |
| |
| Each led is represented as a sub-node of the ti,tca6507 device. |
| |
| LED sub-node properties: |
| - label : (optional) see Documentation/devicetree/bindings/leds/common.txt |
| - reg : number of LED line (could be from 0 to 6) |
| - linux,default-trigger : (optional) |
| see Documentation/devicetree/bindings/leds/common.txt |
| - compatible: either "led" (the default) or "gpio". |
| |
| Examples: |
| |
| tca6507@45 { |
| compatible = "ti,tca6507"; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| reg = <0x45>; |
| |
| gpio-controller; |
| #gpio-cells = <2>; |
| |
| led0: red-aux@0 { |
| label = "red:aux"; |
| reg = <0x0>; |
| }; |
| |
| led1: green-aux@1 { |
| label = "green:aux"; |
| reg = <0x5>; |
| linux,default-trigger = "default-on"; |
| }; |
| |
| wifi-reset@6 { |
| reg = <0x6>; |
| compatible = "gpio"; |
| }; |
| }; |
