Define bindings for stm32 timer trigger
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

+timer trigger bindings for STM32
+
+Must be a sub-node of STM32 general purpose timer driver
+Parent node properties are describe in ../mfd/stm32-general-purpose-timer.txt
+
+Required parameters:
+- compatible: must be "st,stm32-iio-timer"
+- interrupts: Interrupt for this device
+ See ../interrupt-controller/st,stm32-exti.txt
+
+Optional parameters:
+- st,input-triggers-names: List of the possible input triggers for
+ the device
+- st,output-triggers-names: List of the possible output triggers for
+ the device
+
+Possible triggers are defined in include/dt-bindings/iio/timer/st,stm32-timer-trigger.h
+
+Example:
+ gptimer1: gptimer1@40010000 {
+ compatible = "st,stm32-gptimer";
+ reg = <0x40010000 0x400>;
+ clocks = <&rcc 0 160>;
+ clock-names = "clk_int";
+
+ timer1@0 {
+ compatible = "st,stm32-timer-trigger";
+ interrupts = <27>;
+ st,input-triggers-names = TIM5_TRGO,
+ TIM2_TRGO,
+ TIM4_TRGO,
+ TIM3_TRGO;
+ st,output-triggers-names = TIM1_TRGO,
+ TIM1_CH1,
+ TIM1_CH2,
+ TIM1_CH3,
+ TIM1_CH4;
+ };
+ };
