1	TI SOC EHRPWM based PWM controller
2	
3	Required properties:
4	- compatible: Must be "ti,<soc>-ehrpwm".
5	  for am33xx - compatible = "ti,am33xx-ehrpwm";
6	  for da850  - compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
7	- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
8	  the cells format. The only third cell flag supported by this binding is
9	  PWM_POLARITY_INVERTED.
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 EHRPWM:
14	  "ehrpwm<x>", <x> being the 0-based instance number from the HW spec
15	
16	Example:
17	
18	ehrpwm0: ehrpwm@0 { /* EHRPWM on am33xx */
19		compatible = "ti,am33xx-ehrpwm";
20		#pwm-cells = <3>;
21		reg = <0x48300200 0x100>;
22		ti,hwmods = "ehrpwm0";
23	};
24	
25	ehrpwm0: ehrpwm@0 { /* EHRPWM on da850 */
26		compatible = "ti,da850-ehrpwm", "ti,am33xx-ehrpwm";
27		#pwm-cells = <3>;
28		reg = <0x300000 0x2000>;
29	};
