-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.yaml.
-
-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.
-
-Example:
- timer@40002400 {
- compatible = "st,stm32-lptimer";
- ...
- pwm {
- compatible = "st,stm32-pwm-lp";
- #pwm-cells = <3>;
- pinctrl-names = "default", "sleep";
- pinctrl-0 = <&lppwm1_pins>;
- pinctrl-1 = <&lppwm1_sleep_pins>;
- };
- };
