|  | * 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,ap806-odmi-controller", "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,ap806-odmi-controller", | 
|  | "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>; | 
|  | }; |
