Hi Shimoda-san, Thanks for your patch!

That makes perfect sense, as "the R-Car V3U SoC is based on the R-Car Gen 4 architecture".

I think this should be split. The rest looks good to me, but I think it wouldn't hurt to split this patch in two parts: one patch to generalize r8a779a0-sysc.c for R-Car Gen4, and a second patch to introduce support for R-Car S4-8.
