Hi Shimoda-san,

I think this Rep-by can go. Test bot mentioned one build error of v1,
but it didn't report that we should refactor this code.

I'd think this is good enough.

Yes, this may be a little better. I'd think the current naming is good
enough, though.

I also tested this on r8a77965.

I'll check r8a7790 later.

You leave the quirk handling of different ES versions still in
renesas_sdhi_core. I'd think this should also be moved to
renesas_sdhi_internal_dmac? Then we have all the handling in one place.

I'd suggest only a single space (and not a tabulator) before the "=".

Rest looks good so far!

All the best,
