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