+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>;
+		};
+	};
