   1 STMicroelectronics STM32 Low-Power Timer PWM
   2
   3 STM32 Low-Power Timer provides single channel PWM.
   4
   5 Must be a sub-node of an STM32 Low-Power Timer device tree node.
   6 See ../mfd/stm32-lptimer.txt for details about the parent node.
   7
   8 Required parameters:
   9 - compatible:           Must be "st,stm32-pwm-lp".
  10 - #pwm-cells:           Should be set to 3. This PWM chip uses the default 3 cells
  11                         bindings defined in pwm.txt.
  12
  13 Optional properties:
  14 - pinctrl-names:        Set to "default".
  15 - pinctrl-0:            Phandle pointing to pin configuration node for PWM.

  17 Example:
  18         timer@40002400 {
  19                 compatible = "st,stm32-lptimer";
  20                 ...
  21                 pwm {
  22                         compatible = "st,stm32-pwm-lp";
  23                         #pwm-cells = <3>;
  24                         pinctrl-names = "default";
  25                         pinctrl-0 = <&lppwm1_pins>;
  26                 };
  27         };
