    Subject[PATCH v10 15/20] PCI: microchip: Add event IRQ domain ops to struct plda_event
    Date
    For lack of an MSI controller, The new added PCIe interrupts have to be
    added to global interrupt event field. PolarFire event domain ops can
    not be re-used.

    PLDA event domain ops instances will be implemented in later patch.
