Documentation / devicetree / bindings / pwm / pwm-stm32.txt


Based on kernel version 4.16.1. Page generated on 2018-04-09 11:52 EST.

1	STMicroelectronics STM32 Timers PWM bindings
2	
3	Must be a sub-node of an STM32 Timers device tree node.
4	See ../mfd/stm32-timers.txt for details about the parent node.
5	
6	Required parameters:
7	- compatible:		Must be "st,stm32-pwm".
8	- pinctrl-names: 	Set to "default".
9	- pinctrl-0: 		List of phandles pointing to pin configuration nodes for PWM module.
10				For Pinctrl properties see ../pinctrl/pinctrl-bindings.txt
11	
12	Optional parameters:
13	- st,breakinput:	One or two <index level filter> to describe break input configurations.
14				"index" indicates on which break input (0 or 1) the configuration
15				should be applied.
16				"level" gives the active level (0=low or 1=high) of the input signal
17				for this configuration.
18				"filter" gives the filtering value to be applied.
19	
20	Example:
21		timers@40010000 {
22			#address-cells = <1>;
23			#size-cells = <0>;
24			compatible = "st,stm32-timers";
25			reg = <0x40010000 0x400>;
26			clocks = <&rcc 0 160>;
27			clock-names = "int";
28	
29			pwm {
30				compatible = "st,stm32-pwm";
31				pinctrl-0	= <&pwm1_pins>;
32				pinctrl-names	= "default";
33				st,breakinput = <0 1 5>;
34			};
35		};
