Subject: [PATCH v7 0/7] PCI: rcar-gen4: Add R-Car V4H support
Date: Mon, 15 Apr 2024 17:11:28 +0900 [thread overview]
Message-ID: <20240415081135.3814373-1-yoshihiro.shimoda.uh@renesas.com> (raw)
The pcie-rcar-gen4 driver can reuse other R-Car Gen4 support like
r8a779g0 (R-Car V4H) and r8a779h0 (R-Car V4M). However, some
initializing settings differ 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.
About the firmware downloading, we can get information from
the following wiki page:
https://elinux.org/index.php?title=R-Car/Boards/WhiteHawk&oldid=581944#PCIe_firmware
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.
Changes from v6:
https://lore.kernel.org/linux-pci/20240410004832.3726922-1-yoshihiro.shimoda.uh@renesas.com/
- Add Manivannan's Reviewed-by in patch [37]/7.
- Rename a struct from "platdata" to "drvdata" in patch [4/7].
- Revise the commit descriptions in patch [456]/7.
- Rename some functions in patch 6/7.
- Fix the return value of an error path in patch 6/7.
Changes from v5:
https://lore.kernel.org/linux-pci/20240408012458.3717977-1-yoshihiro.shimoda.uh@renesas.com/
- Drop "dwc: " prefixes from the subjects in patch [0456]/7.
Changes from v4:
https://lore.kernel.org/linux-pci/20240403053304.3695096-1-yoshihiro.shimoda.uh@renesas.com/
- Fix compatible string for renesas,r8a779f0-pcie-ep which was described
accidentally from v3...
