Changes in v2:
- s/Low Power/Low-Power
- remove leading 0x in example (parent node)
- improve properties descriptions

+STMicroelectronics STM32 Low-Power Timer quadrature encoder and counter
+
+STM32 Low-Power Timer provides several counter modes. It can be used as:
+- quadrature encoder to detect angular position and direction of rotary
+ elements, from IN1 and IN2 input signals.
+- simple counter from IN1 input signal.
+
+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 properties:
+- compatible: Must be "st,stm32-lptimer-counter".
+- pinctrl-names: Set to "default".
+- pinctrl-0: List of phandles pointing to pin configuration nodes,
+ to set IN1/IN2 pins in mode of operation for Low-Power
+ Timer input on external pin.
+
+Example:
+ lptimer1: lptimer@40002400 {
+ compatible = "st,stm32-lptimer";
+ ...
+ counter {
+ compatible = "st,stm32-lptimer-counter";
+ pinctrl-names = "default";
+ pinctrl-0 = <&lptim1_in_pins>;
+ };
+ };
