-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@...10000 {
-		#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>;
-		};
-	};
