| * 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.yaml |
| for details about the GIC Device Tree binding. |
| |
| 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>; |
| }; |
