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".
- pinctrl-0: Phandle pointing to pin configuration node for PWM.
Example:
timer@40002400 {
compatible = "st,stm32-lptimer";
...
pwm {
compatible = "st,stm32-pwm-lp";
#pwm-cells = <3>;
pinctrl-names = "default";
pinctrl-0 = <&lppwm1_pins>;
};
};
