  17 +Allwinner sun8i-v536 SoC PWM controller
  18 +
  19 +Required properties:
  20 + - compatible: should be "allwinner,<name>-pwm"
  21 +   "allwinner,sun8i-v833-pwm"
  22 +   "allwinner,sun8i-v536-pwm"
  23 +   "allwinner,sun50i-r818-pwm"
  24 +   "allwinner,sun50i-a133-pwm"
  25 +   "allwinner,sun50i-r329-pwm"
  26 + - reg: physical base address and length of the controller's registers
  27 + - #pwm-cells: should be 3. See pwm.txt in this directory for a description of
  28 +   the cells format.
  29 + - clocks: From common clock binding, handle to the parent clock.
  30 + - resets: From reset clock binding, handle to the parent clock.
  31 +
  32 +Example:
  33 +
  34 +       pwm: pwm@300a0000 {
  35 +               compatible = "allwinner,sun50i-r818-pwm";
  36 +               reg = <0x0300a000 0x3ff>;
  37 +               clocks = <&ccu CLK_BUS_PWM>;
  38 +               resets = <&ccu RST_BUS_PWM>;
  39 +               #pwm-cells = <3>;
  40 +       };
