+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>;
+ };
+ };
