    Subject[PATCHv7 08/12] PCI: layerscape: Modify the MSIX to the doorbell mode
    Date
    From: Xiaowei Bao <xiaowei.bao@nxp.com>

    dw_pcie_ep_raise_msix_irq was never called in the exisitng driver
    before, because the ls1046a platform don't support the MSIX feature
    and msix_capable was always set to false.
    Now that add the ls1088a platform with MSIX support, use the doorbell
    method to support the MSIX feature.
