1 NXP PCA9685 16-channel 12-bit PWM LED controller
2 ================================================
3
4 Required properties:
5 - compatible: "nxp,pca9685-pwm"
6 - #pwm-cells: Should be 2. See pwm.yaml in this directory for a description of
7 the cells format.
8 The index 16 is the ALLCALL channel, that sets all PWM channels at the same
9 time.

11 Optional properties:
12 - invert (bool): boolean to enable inverted logic
13 - open-drain (bool): boolean to configure outputs with open-drain structure;
14 if omitted use totem-pole structure

16 Example:
17
18 For LEDs that are directly connected to the PCA, the following setting is
19 applicable:
20
21 pca: pca@41 {
22 compatible = "nxp,pca9685-pwm";
23 #pwm-cells = <2>;
24 reg = <0x41>;
25 invert;
26 open-drain;
27 };
