STMicroelectronics STM32 Timers IIO timer bindings

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.

Example:
	timers@40010000 {
		#address-cells = <1>;
		#size-cells = <0>;
		compatible = "st,stm32-timers";
		reg = <0x40010000 0x400>;
		clocks = <&rcc 0 160>;
		clock-names = "int";

		timer@0 {
			compatible = "st,stm32-timer-trigger";
			reg = <0>;
		};
	};
