[PATCH v6 00/18] dwc MSI fixes, ARTPEC-6 EP mode support, ARTPEC-7 SoC support

[Niklas Cassel]

This is a series that adds:
- PCI endpoint mode support in the ARTPEC-6 driver.
- ARTPEC-7 SoC support in the ARTPEC-6 driver (the SoCs are very similar).
- Small fixes for MSI in designware-ep and designware-host,
  needed to get endpoint mode support working for ARTPEC-6.
- Cleanups in pci-dra7xx to better prepare for endpoint mode in other
  DWC based PCIe drivers.

Changes since V5:
-Dropped GFP_DMA32 from "PCI: dwc: Use the DMA-API to get the MSI address"
 so that we use the exact same GFP flags as before.
-Rewrote commit message for "PCI: dwc: Make cpu_addr_fixup take struct
dw_pcie as argument" to be more detailed.

Niklas Cassel (18):
  PCI: dwc: Use the DMA-API to get the MSI address
  PCI: designware-ep: dw_pcie_ep_set_msi() should only set MMC bits
  PCI: designware-ep: Read-only registers need DBI_RO_WR_EN to be
    writable
  PCI: designware-ep: Pre-allocate memory for MSI in dw_pcie_ep_init
  PCI: designware-ep: Remove static keyword from dw_pcie_ep_reset_bar()
  PCI: designware-ep: Add generic function for raising MSI irq
  PCI: dwc: dra7xx: Refactor Kconfig and Makefile handling for host/ep
    mode
  PCI: dwc: dra7xx: Assign pp->ops in dra7xx_add_pcie_port() rather than
    in probe
  PCI: dwc: dra7xx: Help compiler to remove unused code
  PCI: dwc: artpec6: Remove unused defines
  PCI: dwc: artpec6: Use BIT and GENMASK macros
  PCI: dwc: artpec6: Split artpec6_pcie_establish_link() into smaller
    functions
  bindings: PCI: artpec: Add support for endpoint mode
  PCI: dwc: artpec6: Add support for endpoint mode
  PCI: dwc: Make cpu_addr_fixup take struct dw_pcie as argument
  PCI: dwc: artpec6: Deassert the core before waiting for PHY
  bindings: PCI: artpec: Add support for the ARTPEC-7 SoC
  PCI: dwc: artpec6: Add support for the ARTPEC-7 SoC
