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>;
|
|
};
|
|
};
