Subject: [PATCH v5 0/2] PCI: dwc: fix two MSI issues
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 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 seperate 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
