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";
|
|
};
|
|
};
