| 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. |
| |
| 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>; |
| }; |
| }; |
