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.
