+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>;
+ };
+ };
