-Must be a sub-node of an STM32 Timers device tree node.
-See ../mfd/stm32-timers.txt for details about the parent node.

-Required parameters:
-- compatible:	Must be one of:
-		"st,stm32-timer-trigger"
-		"st,stm32h7-timer-trigger"
-- reg:		Identify trigger hardware block.

-		#size-cells = <0>;
-		compatible = "st,stm32-timers";
-		reg = <0x40010000 0x400>;
