PCI: rcar-gen4: Add R-Car V4H support
|
expand
|
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 binary, please refer to the following patch descirption: PCI: rcar-gen4: Add support for r8a779g0 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 v7: https://lore.kernel.org/linux-pci/20240415081135.3814373-1-yoshihiro.shimoda.uh@renesas.com/ - Since the following patches are merged into pci.git / dt-bindings branch, drop them from this patch series: dt-bindings: PCI: rcar-gen4-pci-host: Add R-Car V4H compatible dt-bindings: PCI: rcar-gen4-pci-ep: Add R-Car V4H compatible - Add Reviewed-by in the patch [25]/5. - Add a condition to avoid automated tools report in the patch 2/5. - Change the new function which adds an "enable" flag in the patch 3/5. So, change the commit description and move some functions' places. - Revise the commit description and add firmware information in detail in the patch 4/5. - Use the offset directly instead of definitions in the patch 4/5. - Add comments for some magical offsets/values in the patch 4/5. - Change error message when request_firmware() failed in the patch 4/5. 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...
