|
|
|

- compatible: "nxp,pca9685-pwm"
|
|
- #pwm-cells: Should be 2. See pwm.yaml in this directory for a description of

For LEDs that are directly connected to the PCA, the following setting is
|
|

|
|
|
|
pca: pca@41 {
|
|
compatible = "nxp,pca9685-pwm";
|
|
#pwm-cells = <2>;
|
|
reg = <0x41>;
|
|
invert;
|
|
open-drain;
