STMicroelectronics STM32 Low-Power Timer Trigger



STM32 Low-Power Timer provides trigger source (LPTIM output) that can be used

by STM32 internal ADC and/or DAC.



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 properties:

- compatible:		Must be "st,stm32-lptimer-trigger".

- reg:			Identify trigger hardware block. Must be 0, 1 or 2

			respectively for lptimer1, lptimer2 or lptimer3

			trigger output.



Example:

	timer@40002400 {

		compatible = "st,stm32-lptimer";

		...

		trigger@0 {

			compatible = "st,stm32-lptimer-trigger";

			reg = <0>;

		};

	};
