[PATCH v8 3/8] PWM: add pwm-stm32 DT bindings

Show all headers | View raw

Define bindings for pwm-stm32

version 8:
- reword st,breakinput description.

version 6:
- change st,breakinput parameter format to make it usuable on stm32f7 too.

version 2:
- use parameters instead of compatible of handle the hardware configuration

+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>;
+		};
+	};
