Sorry, I missed that in my review.
I agree that the renesas,sdhi-r8a77965 is not needed.

One more consideration.
With the current state of the driver this patch should be fine,
modulo the changes suggested above. But once HS400 support is merged
some logic will be required to disable that feature for the r8a77965
until HS400 support for that SoC is explicitly added.
Or conversely, perhaps when HS400 is added it should only be enabled
in the driver for SoCs that are known to work: r8a7796 and r8a7795. In the
case of the latter perhaps only ES2.0.
Wolfram, what do you think?
