Thanks!

I actually wrote such a patch a while back.
However, I didn't send it after discovering the R-Car V3U Series
User’s Manual Rev. 0.50 does not mention the fourth Strobe Timing
Adjustment bit (STRTIM) in the RPC-IF PHY Control Register (PHYCNT),
which is present on R-Car S4-8 and V4H, but not on R-Car Gen3.

Gr{oetje,eeting}s,
