+STMicroelectronics PWM driver bindings for STM32
+--------------------------------------
+
+Must be a child of STM32 multifunctions timer driver
+
+Required parameters:
+- compatible : "st,stm32-pwm1"
+ "st,stm32-pwm2"
+ "st,stm32-pwm3"
+ "st,stm32-pwm4"
+ "st,stm32-pwm5"
+ "st,stm32-pwm8"
+ "st,stm32-pwm9"
+ "st,stm32-pwm10"
+ "st,stm32-pwm11"
+ "st,stm32-pwm12"
+ "st,stm32-pwm13"
+ "st,stm32-pwm14"
+- pinctrl-names: Set to "default".
+- pinctrl-0: List of phandles pointing to pin configuration nodes
+ for PWM module.
+ For Pinctrl properties, please refer to [1].
+
+Optional parameters:
+- st,breakinput-polarity if set enable break input feature.
+ The value define the active polarity:
+ - 0 (active LOW)
+ - 1 (active HIGH)
+
+[1] Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+Example:
+ mfd_timer1: mfdtimer1@40010000 {
+ compatible = "st,stm32-mfd-timer1";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "mfd_timer_clk";
+ interrupts = <27>;
+
+ pwm1: pwm1@40010000 {
+ compatible = "st,stm32-pwm1";
+ };
+ };
