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.
