Required properties:
- compatible: Must be "ti,<soc>-ecap".
- for am33xx - compatible = "ti,am33xx-ecap";
- for da850 - compatible = "ti,da850-ecap", "ti,am33xx-ecap";
+ for am33xx - compatible = "ti,am3352-ecap", "ti,am33xx-ecap";

- #pwm-cells: should be 3. See pwm.txt in this directory for a description of
the cells format. The PWM channel index ranges from 0 to 4. The only third
cell flag supported by this binding is PWM_POLARITY_INVERTED.
- reg: physical base address and size of the registers map.
Optional properties:
-- ti,hwmods: Name of the hwmod associated to the ECAP:
- "ecap<x>", <x> being the 0-based instance number from the HW spec
+- clocks: Handle to the ECAP's functional clock.
+- clock-names: Must be set to "fck".
Example:
