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.
