LEDs connected to pca9632, pca9633 or pca9634
Required properties:
- compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
Optional properties:
- nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
to open-drain, newer chips to totem pole)
- nxp,hw-blink : use hardware blinking instead of software blinking
- nxp,period-scale : In some configurations, the chip blinks faster than expected.
This parameter provides a scaling ratio (fixed point, decimal divided
by 1000) to compensate, e.g. 1300=1.3x and 750=0.75x.
- nxp,inverted-out: invert the polarity of the generated PWM
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,
0 to 7 in pca9634, or 0 to 15 in pca9635)
- 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>;
red@0 {
label = "red";
reg = <0>;
linux,default-trigger = "none";
};
green@1 {
label = "green";
reg = <1>;
linux,default-trigger = "none";
};
blue@2 {
label = "blue";
reg = <2>;
linux,default-trigger = "none";
};
unused@3 {
label = "unused";
reg = <3>;
linux,default-trigger = "none";
};
};
