Subject: [PATCH v3 3/6] dt-bindings: iio: document interrupt trigger support
Date: Tue, 28 Feb 2017 17:51:16 +0100 [thread overview]
Message-ID: <1488300679-3259-4-git-send-email-fabrice.gasnier@st.com> (raw)
In-Reply-To: <1488300679-3259-1-git-send-email-fabrice.gasnier@st.com>
Document interrupt trigger that takes a generic interrupt, and
can be used as trigger source for sampling devices such as sensors,
ADCs...

+Interrupt based trigger
+
+Any internal or external interrupt may be used as trigger source for
+devices like sensors, ADCs... As an example, external signal can be
+routed to a GPIO, and turned into an interrupt driven trigger.
+
+Required properties:
+- compatible: Should be "interrupt-trigger"
+- interrupts: The interrupt used as trigger. Generic interrupt client node as
+ described in ../../interrupt-controller/interrupts.txt
+
+Optional properties:
+- #io-trigger-cells = <0>; See the IIO bindings, IIO trigger providers
+ and consumers sections in ../iio-bindings.txt
+
+Example:
+ trig0: interrupt-trigger0 {
+ #io-trigger-cells = <0>;
+ compatible = "interrupt-trigger";
+ interrupts = <11 0>;
+ interrupt-parent = <&gpioa>;
+ }
