Define bindings for STM32 timer trigger

version 8:
- reword "reg" parameter description

version 4:
- remove triggers enumeration from DT
- add reg parameter

version 3:
- change file name
- add cross reference with mfd bindings

version 2:
- only keep one compatible
- add DT parameters to set lists of the triggers:
  one list describe the triggers created by the device
  another one give the triggers accepted by the device

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