-TI SOC EHRPWM based PWM controller
-
-Required properties:
-- compatible: Must be "ti,<soc>-ehrpwm".
-  for am33xx  - compatible = "ti,am3352-ehrpwm";
-  for am4372  - compatible = "ti,am4372-ehrpwm", "ti-am3352-ehrpwm";
-  for am654   - compatible = "ti,am654-ehrpwm", "ti-am3352-ehrpwm";
-  for da850   - compatible = "ti,da850-ehrpwm", "ti-am3352-ehrpwm";
-  for dra746 - compatible = "ti,dra746-ehrpwm", "ti-am3352-ehrpwm";
-- #pwm-cells: should be 3. See pwm.yaml in this directory for a description of
-  the cells format. The only third cell flag supported by this binding is
-  PWM_POLARITY_INVERTED.
-- reg: physical base address and size of the registers map.
-- clocks: Handle to the PWM's time-base and functional clock.
-- clock-names: Must be set to "tbclk" and "fck".
