LEDs connected to pca9632, pca9633 or pca9634
|
|
|
|
Required properties:
|
|
- compatible : should be : "nxp,pca9632", "nxp,pca9633" or "nxp,pca9634"
|
|
|
|
Optional properties:
|
|
- nxp,totem-pole : use totem pole (push-pull) instead of default open-drain
|
|
- nxp,hw-blink : use hardware blinking instead of software blinking
|
|
|
|
Each led is represented as a sub-node of the nxp,pca963x device.
|
|
|
|
LED sub-node properties:
|
|
- label : (optional) see Documentation/devicetree/bindings/leds/common.txt
|
|
- reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633
|
|
or 0 to 7 in pca9634)
|
|
- linux,default-trigger : (optional)
|
|
see Documentation/devicetree/bindings/leds/common.txt
|
|
|
|
Examples:
|
|
|
|
pca9632: pca9632 {
|
|
compatible = "nxp,pca9632";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
reg = <0x62>;
