Subject: [PATCH 0/6] PCI: dwc: rcar-gen4: Add R-Car V4H support
Date: Thu, 29 Feb 2024 21:07:13 +0900	[thread overview]
Message-ID: <20240229120719.2553638-1-yoshihiro.shimoda.uh@renesas.com> (raw)

The pcie-rcar-gen4 driver can reuse other R-Car Gen4 support. However,
some initializing settings differs between R-Car S4-8 (r8a779f0) and
others. The R-Car S4-8 will be minority about the setting way. So,
R-Car V4H will be majority and this is generic initialization way
as "renesas,rcar-gen4-pcie{-ep}" compatible. For now, I tested
both R-Car S4-8 and R-Car V4H on this driver. I'll support one more
other SoC (R-Car V4M) in the future.

  dt-bindings: PCI: rcar-gen4-pci-host: Add R-Car V4H compatible
  dt-bindings: PCI: rcar-gen4-pci-ep: Add R-Car V4H compatible
  PCI: dwc: Add PCIE_PORT_{FORCE,LANE_SKEW} macros
  PCI: dwc: rcar-gen4: Add a new function pointer for other SoC support
  PCI: dwc: rcar-gen4: Add support for other R-Car Gen4 PCIe controller
  misc: pci_endpoint_test: Add Device ID for R-Car V4H PCIe controller
