1LEDs connected to tca6507
2
3Required properties:
4- compatible : should be : "ti,tca6507".
5- #address-cells: must be 1
6- #size-cells: must be 0
7- reg: typically 0x45.
8
9Optional properties:
10- gpio-controller: allows lines to be used as output-only GPIOs.
11- #gpio-cells: if present, must not be 0.
12
13Each led is represented as a sub-node of the ti,tca6507 device.
14
15LED sub-node properties:
16- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
17- reg : number of LED line (could be from 0 to 6)
18- linux,default-trigger : (optional)
