+NXP PCA9685 16-channel 12-bit PWM LED controller
+================================================
+
+Required properties:
+ - compatible: "nxp,pca9685-pwm"
+ - #pwm-cells: Should be 2. See pwm.yaml 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;
+};
