1	TI SOC ECAP based APWM controller
2	
3	Required properties:
4	- compatible: Must be "ti,<soc>-ecap".
5	  for am33xx - compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
6	  for am4372 - compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
7	  for da850  - compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
8	  for dra746 - compatible = "ti,dra746-ecap", "ti,am3352-ecap";
9	- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
10	  the cells format. The PWM channel index ranges from 0 to 4. The only third
11	  cell flag supported by this binding is PWM_POLARITY_INVERTED.
12	- reg: physical base address and size of the registers map.
13	
14	Optional properties:
15	- clocks: Handle to the ECAP's functional clock.
16	- clock-names: Must be set to "fck".
17	
18	Example:
19	
20	ecap0: ecap@48300100 { /* ECAP on am33xx */
21		compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
22		#pwm-cells = <3>;
23		reg = <0x48300100 0x80>;
24		clocks = <&l4ls_gclk>;
25		clock-names = "fck";
26	};
27	
28	ecap0: ecap@48300100 { /* ECAP on am4372 */
29		compatible = "ti,am4372-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
30		#pwm-cells = <3>;
31		reg = <0x48300100 0x80>;
32		ti,hwmods = "ecap0";
33		clocks = <&l4ls_gclk>;
34		clock-names = "fck";
35	};
36	
37	ecap0: ecap@1f06000 { /* ECAP on da850 */
38		compatible = "ti,da850-ecap", "ti,am3352-ecap", "ti,am33xx-ecap";
39		#pwm-cells = <3>;
40		reg = <0x1f06000 0x80>;
41	};
42	
43	ecap0: ecap@4843e100 {
44		compatible = "ti,dra746-ecap", "ti,am3352-ecap";
45		#pwm-cells = <3>;
46		reg = <0x4843e100 0x80>;
47		clocks = <&l4_root_clk_div>;
48		clock-names = "fck";
49	};
