| |
Fix two MSI issues. One to skip PCIE_MSI_INTR0* programming if MSI is disabled, another to use an address in the driver data for MSI address, to fix the MSI page leakage during suspend/resume.
Since v6: - Keep the IS_ENABLED(CONFIG_PCI_MSI) check in dw_pcie_msi_init().
Since v5: - rebase on pci/dwc branch - add Acked-by tag
Since v4: - fix pci-dra7xx.c
Since v3: - add Acked-by tag - change patch2 commit msg to make it clear - map the MSI msg with dma_map_single_attrs() for some platforms which either has separate addrs for dma and phy or has mem access limitation for the PCIe.
Since v2: - add Acked-by tag - use an address in the driver data for MSI address. Thank Ard and Rob for pointing out this correct direction. - Since the MSI page has gone, the leak issue doesn't exist anymore, remove unnecessary patches. - Remove dw_pcie_free_msi rename and the last patch. They could be targeted to next. So will send out patches in a separate series.
Since v1: - add proper error handling patches. - solve the msi page leakage by moving dw_pcie_msi_init() from each users to designware host
