   1 TI SOC ECAP based APWM controller
   2
   3 Required properties:
   4 - compatible: Must be "ti,<soc>-ecap".
   5   for am33xx - compatible = "ti,am33xx-ecap";
   6   for da850  - compatible = "ti,da850-ecap", "ti,am33xx-ecap";
   7 - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
   8   the cells format. The PWM channel index ranges from 0 to 4. The only third
   9   cell flag supported by this binding is PWM_POLARITY_INVERTED.
  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 { /* ECAP on am33xx */
  19         compatible = "ti,am33xx-ecap";
  20         #pwm-cells = <3>;
  21         reg = <0x48300100 0x80>;
  22         ti,hwmods = "ecap0";
  23 };
  24
  25 ecap0: ecap@0 { /* ECAP on da850 */
  26         compatible = "ti,da850-ecap", "ti,am33xx-ecap";
  27         #pwm-cells = <3>;
  28         reg = <0x306000 0x80>;
  29 };
