So I'm inclined to replace all of them by R8A779H0_CLK_VIOBUSD2 while applying, which would match R-Car V4H.
What do you mean with the above? First you say the clock parents should be some form of S0Dx_VIO, but then you say you'll use VIOBUSD2. Aren't those unrelated clocks, from different PLLs?
Are you OK with that?
I'm fine with that. I can't really get much out of the docs wrt. clocking, and the clocks I used were from the BSP. Afaics, it looks similar to V4H, so it's probably best have the same clocks, as you suggest.
