1TI SOC ECAP based APWM controller
2
3Required 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  for 66ak2g - compatible = "ti,k2g-ecap", "ti,am3352-ecap";
10  for am654  - compatible = "ti,am654-ecap", "ti,am3352-ecap";
11- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of
12  the cells format. The PWM channel index ranges from 0 to 4. The only third
13  cell flag supported by this binding is PWM_POLARITY_INVERTED.
14- reg: physical base address and size of the registers map.
15
16Optional properties:
17- clocks: Handle to the ECAP's functional clock.
18- clock-names: Must be set to "fck".

23	compatible = "ti,am3352-ecap", "ti,am33xx-ecap";
24	#pwm-cells = <3>;
25	reg = <0x48300100 0x80>;
26	clocks = <&l4ls_gclk>;
27	clock-names = "fck";
28};
