NXP PCA9685 16-channel 12-bit PWM LED controller
================================================
Required properties:
- compatible: "nxp,pca9685-pwm"
- #pwm-cells: Should be 2. See pwm.txt in this directory for a description of
the cells format.
The index 16 is the ALLCALL channel, that sets all PWM channels at the same
time.
Optional properties:
- invert (bool): boolean to enable inverted logic
- open-drain (bool): boolean to configure outputs with open-drain structure;
if omitted use totem-pole structure
Example:
For LEDs that are directly connected to the PCA, the following setting is
applicable:
pca: pca@41 {
compatible = "nxp,pca9685-pwm";
#pwm-cells = <2>;
reg = <0x41>;
invert;
open-drain;
};
