description:
  Some Marvell SoCs have an On-Die Message Interrupt (ODMI) controller which can
  be used by on-board peripherals for MSI interrupts.

properties:
  compatible:
    const: marvell,odmi-controller

  reg:
    description: List of register definitions, one for each ODMI frame.

  msi-controller: true

  marvell,odmi-frames:
    description: Number of ODMI frames available. Each frame provides a number of events.
    $ref: /schemas/types.yaml#/definitions/uint32

  marvell,spi-base:
    description: >
      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.
