1 LEDs connected to pca9632, pca9633 or pca9634
2
3 Required properties:
4 - compatible : should be : "nxp,pca9632", "nxp,pca9633", "nxp,pca9634" or "nxp,pca9635"
5
6 Optional properties:
7 - nxp,totem-pole : use totem pole (push-pull) instead of open-drain (pca9632 defaults
8 to open-drain, newer chips to totem pole)
9 - nxp,hw-blink : use hardware blinking instead of software blinking
10 - nxp,period-scale : In some configurations, the chip blinks faster than expected.
11 This parameter provides a scaling ratio (fixed point, decimal divided
12 by 1000) to compensate, e.g. 1300=1.3x and 750=0.75x.
13 - nxp,inverted-out: invert the polarity of the generated PWM
14
15 Each led is represented as a sub-node of the nxp,pca963x device.
16
17 LED sub-node properties:
18 - label : (optional) see Documentation/devicetree/bindings/leds/common.txt
19 - reg : number of LED line (could be from 0 to 3 in pca9632 or pca9633,
20 0 to 7 in pca9634, or 0 to 15 in pca9635)
21 - linux,default-trigger : (optional)
22 see Documentation/devicetree/bindings/leds/common.txt

24 Examples:

26 pca9632: pca9632 {
27 compatible = "nxp,pca9632";
28 #address-cells = <1>;
29 #size-cells = <0>;
30 reg = <0x62>;
31
32 red@0 {
33 label = "red";
34 reg = <0>;
35 linux,default-trigger = "none";
36 };
37 green@1 {
38 label = "green";
39 reg = <1>;
40 linux,default-trigger = "none";
41 };
42 blue@2 {
43 label = "blue";
44 reg = <2>;
45 linux,default-trigger = "none";
46 };
47 unused@3 {
48 label = "unused";
49 reg = <3>;
50 linux,default-trigger = "none";
51 };
52 };
