1 STMicroelectronics STM32 Low-Power Timer quadrature encoder and counter
3 STM32 Low-Power Timer provides several counter modes. It can be used as:
4 - quadrature encoder to detect angular position and direction of rotary
5 elements, from IN1 and IN2 input signals.
6 - simple counter from IN1 input signal.
8 Must be a sub-node of an STM32 Low-Power Timer device tree node.
9 See ../mfd/stm32-lptimer.txt for details about the parent node.
12 - compatible: Must be "st,stm32-lptimer-counter".
13 - pinctrl-names: Set to "default". An additional "sleep" state can be
14 defined to set pins in sleep state.
15 - pinctrl-n: List of phandles pointing to pin configuration nodes,
16 to set IN1/IN2 pins in mode of operation for Low-Power
17 Timer input on external pin.
