   1 TI SOC ECAP based APWM controller
   2
   3 Required properties:
   4 - compatible: Must be "ti,am33xx-ecap"
   5 - #pwm-cells: Should be 3. Number of cells being used to specify PWM property.
   6   First cell specifies the per-chip index of the PWM to use, the second
   7   cell is the period in nanoseconds and bit 0 in the third cell is used to
   8   encode the polarity of PWM output. Set bit 0 of the third in PWM specifier
   9   to 1 for inverse polarity & set to 0 for normal polarity.
  10 - reg: physical base address and size of the registers map.
  11
  12 Optional properties:
  13 - ti,hwmods: Name of the hwmod associated to the ECAP:
  14   "ecap<x>", <x> being the 0-based instance number from the HW spec
  15
  16 Example:
  17
  18 ecap0: ecap@0 {
  19         compatible = "ti,am33xx-ecap";
  20         #pwm-cells = <3>;
  21         reg = <0x48300100 0x80>;
  22         ti,hwmods = "ecap0";
  23 };
