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.txt 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
15	
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	};
