| STMicroelectronics STM32 Low-Power Timer |
| |
| The STM32 Low-Power Timer (LPTIM) is a 16-bit timer that provides several |
| functions: |
| - PWM output (with programmable prescaler, configurable polarity) |
| - Quadrature encoder, counter |
| - Trigger source for STM32 ADC/DAC (LPTIM_OUT) |
| |
| Required properties: |
| - compatible: Must be "st,stm32-lptimer". |
| - reg: Offset and length of the device's register set. |
| - clocks: Phandle to the clock used by the LP Timer module. |
| - clock-names: Must be "mux". |
| - #address-cells: Should be '<1>'. |
| - #size-cells: Should be '<0>'. |
| |
| Optional subnodes: |
| - pwm: See ../pwm/pwm-stm32-lp.txt |
| - counter: See ../iio/timer/stm32-lptimer-cnt.txt |
| - trigger: See ../iio/timer/stm32-lptimer-trigger.txt |
| |
| Example: |
| |
| timer@40002400 { |
| compatible = "st,stm32-lptimer"; |
| reg = <0x40002400 0x400>; |
| clocks = <&timer_clk>; |
| clock-names = "mux"; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| |
| pwm { |
| compatible = "st,stm32-pwm-lp"; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&lppwm1_pins>; |
| }; |
| |
| trigger@0 { |
| compatible = "st,stm32-lptimer-trigger"; |
| reg = <0>; |
| }; |
| |
| counter { |
| compatible = "st,stm32-lptimer-counter"; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&lptim1_in_pins>; |
| }; |
| }; |
