1	TI SOC ECAP based APWM controller
2	
3	Required properties:
4	- compatible: Must be "ti,am33xx-ecap"
5	- #pwm-cells: Should be 3. Number of cells being used to specify PWM property.
6	  First cell specifies the per-chip index of the PWM to use, the second
7	  cell is the period in nanoseconds and bit 0 in the third cell is used to
8	  encode the polarity of PWM output. Set bit 0 of the third in PWM specifier
9	  to 1 for inverse polarity & set to 0 for normal polarity.
10	- reg: physical base address and size of the registers map.
11	
12	Optional properties:
13	- ti,hwmods: Name of the hwmod associated to the ECAP:
14	  "ecap<x>", <x> being the 0-based instance number from the HW spec
15	
16	Example:
17	
18	ecap0: ecap@0 {
19		compatible = "ti,am33xx-ecap";
20		#pwm-cells = <3>;
21		reg = <0x48300100 0x80>;
22		ti,hwmods = "ecap0";
23	};
