Hello, > 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. Applied to dt-bindings, thank you!
