STMicroelectronics STM32 Low-Power Timer PWM
STM32 Low-Power Timer provides single channel PWM.
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 parameters:
- compatible: Must be "st,stm32-pwm-lp".
- #pwm-cells: Should be set to 3. This PWM chip uses the default 3 cells
bindings defined in pwm.txt.
Optional properties:
- pinctrl-names: Set to "default". An additional "sleep" state can be
defined to set pins in sleep state when in low power.
- pinctrl-n: Phandle(s) pointing to pin configuration node for PWM,
respectively for "default" and "sleep" states.
