+STMicroelectronics STM32 Timer quadrature encoder
+
+STM32 Timer provides quadrature encoder to detect
+angular position and direction of rotary elements,
+from IN1 and IN2 input signals.
+
+Must be a sub-node of an STM32 Timer device tree node.
+See ../mfd/stm32-timers.txt for details about the parent node.
+
+Required properties:
+- compatible: Must be "st,stm32-timer-counter".
+- pinctrl-names: Set to "default".
+- pinctrl-0: List of phandles pointing to pin configuration nodes,
+ to set CH1/CH2 pins in mode of operation for STM32
+ Timer input on external pin.
+
+Example:
+ timers@40010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "st,stm32-timers";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "int";
+
+ counter {
+ compatible = "st,stm32-timer-counter";
+ pinctrl-names = "default";
+ pinctrl-0 = <&tim1_in_pins>;
+ };
