+* Marvell ODMI for MSI support
+
+Some Marvell SoCs have an On-Die Message Interrupt (ODMI) controller
+which can be used by on-board peripheral for MSI interrupts.
+
+Required properties:
+
+- compatible : The value here should contain "marvell,odmi-controller".
+
+- interrupt,controller : Identifies the node as an interrupt controller.
+
+- msi-controller : Identifies the node as an MSI controller.
+
+- marvell,odmi-frames : Number of ODMI frames available. Each frame
+ provides a number of events.
+
+- reg : List of register definitions, one for each
+ ODMI frame.
+
+- marvell,spi-base : List of GIC base SPI interrupts, one for each
+ ODMI frame. Those SPI interrupts are 0-based,
+ i.e marvell,spi-base = <128> will use SPI #96.
+ See Documentation/devicetree/bindings/interrupt-controller/arm,gic.txt
+ for details about the GIC Device Tree binding.
+
+- interrupt-parent : Reference to the parent interrupt controller.
+
+Example:
+
+ odmi: odmi@300000 {
+ compatible = "marvell,odmi-controller";
+ interrupt-controller;
+ msi-controller;
+ marvell,odmi-frames = <4>;
+ reg = <0x300000 0x4000>,
+ <0x304000 0x4000>,
+ <0x308000 0x4000>,
+ <0x30C000 0x4000>;
+ marvell,spi-base = <128>, <136>, <144>, <152>;
+ };
