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".
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";
};
};
