[PATCH v4 00/17] dwc MSI fixes, ARTPEC-6 EP mode support, ARTPEC-7 SoC support

From: Niklas Cassel
Date: Fri Nov 03 2017 - 09:47:47 EST


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.

New in V4:
Fixed all commit messages so that they are readable without the title.
Replaced ifdefs in pci-dra7xx and pcie-artpec6 by using the
IS_ENABLED macro. (Thanks Arnd!)

Niklas Cassel (17):
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
bindings: PCI: artpec: Add support for the ARTPEC-7 SoC
PCI: dwc: artpec6: Add support for the ARTPEC-7 SoC
