STMicroelectronics STM32 Timers PWM bindings

Must be a sub-node of an STM32 Timers device tree node.
See ../mfd/stm32-timers.txt for details about the parent node.

Required parameters:
- compatible:		Must be "st,stm32-pwm".
- pinctrl-names: 	Set to "default".
- pinctrl-0: 		List of phandles pointing to pin configuration nodes for PWM module.
			For Pinctrl properties see ../pinctrl/pinctrl-bindings.txt

Optional parameters:
- st,breakinput:	One or two <index level filter> to describe break input configurations.
			"index" indicates on which break input (0 or 1) the configuration
			should be applied.
			"level" gives the active level (0=low or 1=high) of the input signal
			for this configuration.
			"filter" gives the filtering value to be applied.

Example:
	timers@40010000 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "st,stm32-timers";
		reg = <0x40010000 0x400>;
		clocks = <&rcc 0 160>;
		clock-names = "int";

		pwm {
			compatible = "st,stm32-pwm";
			pinctrl-0	= <&pwm1_pins>;
			pinctrl-names	= "default";
			st,breakinput = <0 1 5>;
		};
	};
