STMicroelectronics STM32 Low-Power Timer PWM



STM32 Low-Power Timer provides single channel PWM.



Must be a sub-node of an STM32 Low-Power Timer device tree node.

See ../mfd/stm32-lptimer.txt for details about the parent node.



Required parameters:

- compatible:		Must be "st,stm32-pwm-lp".



Optional properties:

- pinctrl-names: 	Set to "default".

- pinctrl-0: 		Phandle pointing to pin configuration node for PWM.



Example:

	timer@40002400 {

		compatible = "st,stm32-lptimer";

		...

		pwm {

			compatible = "st,stm32-pwm-lp";

			pinctrl-names = "default";

			pinctrl-0 = <&lppwm1_pins>;

		};

	};
