1 NXP PCA9685 16-channel 12-bit PWM LED controller
2 ================================================
5 - compatible: "nxp,pca9685-pwm"
6 - #pwm-cells: should be 2. The first cell specifies the per-chip index
7 of the PWM to use and the second cell is the period in nanoseconds.
8 The index 16 is the ALLCALL channel, that sets all PWM channels at the same
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
18 For LEDs that are directly connected to the PCA, the following setting is
22 compatible = "nxp,pca9685-pwm";
