+TI SOC ECAP based APWM controller
+
+Required properties:
+- compatible: Must be "ti,am33xx-ecap"
+- #pwm-cells: Should be 3. Number of cells being used to specify PWM property.
+ First cell specifies the per-chip index of the PWM to use, the second
+ cell is the period in nanoseconds and bit 0 in the third cell is used to
+ encode the polarity of PWM output. Set bit 0 of the third in PWM specifier
+ to 1 for inverse polarity & set to 0 for normal polarity.
+- 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
+
+Example:
+
+ecap0: ecap@0 {
+ compatible = "ti,am33xx-ecap";
+ #pwm-cells = <3>;
+ reg = <0x48300100 0x80>;
+ ti,hwmods = "ecap0";
+};
