[PATCH 3/5] Documentation: dt: iio: document stm32 exti trigger

Show all headers | View raw

Add dt documentation for st,stm32-exti-trigger.
EXTi gpio signal can be routed internally as trigger source for various
IPs (e.g. for ADC or DAC conversions).

+STMicroelectronics STM32 EXTI trigger bindings
+
+EXTi gpio signal can be routed internally as trigger source for various
+IPs (e.g. for ADC or DAC conversions).
+
+Contents of a stm32 exti trigger root node:
+-------------------------------------------
+Required properties:
+- compatible: Should be "st,stm32-exti-trigger"
+- extiN-gpio: optional gpio line that may be used as external trigger source
+  (e.g. N may be 0..15. For example, exti11-gpio can trig ADC on stm32f4).
+
+Example:
+	triggers {
+		compatible = "st,stm32-exti-trigger";
+		exti11-gpio=<&gpioa 11 0>;
+	};
