From: Xiaowei Bao <xiaowei.bao@xxxxxxx> 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.
