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 not 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".
|
||
|
|
|
