Subject: [PATCH v5 0/7] PCI: dwc: rcar-gen4: Add R-Car V4H support
Date: Mon, 8 Apr 2024 10:24:51 +0900 [thread overview]
Message-ID: <20240408012458.3717977-1-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. 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 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...
Changes from v3:
https://lore.kernel.org/linux-pci/20240401023942.134704-1-yoshihiro.shimoda.uh@renesas.com/
- Modify the code to use "do .. while" instead of goto in patch 6/7.
Changes from v2:
https://lore.kernel.org/linux-pci/20240326024540.2336155-1-yoshihiro.shimoda.uh@renesas.com/
- Add a new patch which just add a platdata in patch 4/7.
- Modify the subjects in patch [56]/7.
- Modify the description and code about Bjorn's comment in patch [56]/7.
- Add missing MODULE_FIRMWARE(9 in patch 6/7.
- Document a policy aboud adding pci_device_id instead of adding r8a779g0's id
in patch 7/7.
Changes from v1:
https://lore.kernel.org/linux-pci/20240229120719.2553638-1-yoshihiro.shimoda.uh@renesas.com/
- Based on v6.9-rc1.
- Add Acked-by and/or Reviewed-by in patch [126/6].
