+STMicroelectronics STM32 Low-Power Timer
+
+The STM32 Low-Power Timer (LPTIM) is a 16-bit timer that provides several
+functions:
+- PWM output (with programmable prescaler, configurable polarity)
+- Quadrature encoder, counter
+- Trigger source for STM32 ADC/DAC (LPTIM_OUT)
+
+Required properties:
+- compatible: Must be "st,stm32-lptimer".
+- reg: Offset and length of the device's register set.
+- clocks: Phandle to the clock used by the LP Timer module.
+- clock-names: Must be "mux".
+- #address-cells: Should be '<1>'.
+- #size-cells: Should be '<0>'.
+
+Optional subnodes:
+- pwm: See ../pwm/pwm-stm32-lp.txt
+- counter: See ../iio/timer/stm32-lptimer-cnt.txt
+- trigger: See ../iio/timer/stm32-lptimer-trigger.txt
+
+Example:
+
+ timer@40002400 {
+ compatible = "st,stm32-lptimer";
+ reg = <0x40002400 0x400>;
+ clocks = <&timer_clk>;
+ clock-names = "mux";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ pwm {
+ compatible = "st,stm32-pwm-lp";
+ pinctrl-names = "default";
+ pinctrl-0 = <&lppwm1_pins>;
+ };
+
+ trigger@0 {
+ compatible = "st,stm32-lptimer-trigger";
+ reg = <0>;
+ };
+
+ counter {
+ compatible = "st,stm32-lptimer-counter";
+ pinctrl-names = "default";
+ pinctrl-0 = <&lptim1_in_pins>;
+ };
+ };
