Define bindings for STM32 timer trigger
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 General Purpose Timer IIO timer bindings
+
+Must be a sub-node of an STM32 General Purpose Timer device tree node.
+See ../mfd/stm32-general-purpose-timer.txt for details about the parent node.
+
+Required parameters:
+- compatible: Must be "st,stm32-timer-trigger".
+- reg: Define triggers configuration of the hardware IP.
+
+Example:
+ timers@40010000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "st,stm32-gptimer";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "clk_int";
+
+ timer@0 {
+ compatible = "st,stm32-timer-trigger";
+ reg = <0>;
+ };
+ };
