Subject: [PATCH v6 08/11] PCI: layerscape: Modify the MSIX to the doorbell mode
Date: Sat, 14 Mar 2020 11:30:35 +0800
Message-ID: <20200314033038.24844-9-xiaowei.bao@nxp.com> (raw)
In-Reply-To: <20200314033038.24844-1-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.
