The SDHI/MMC controller in the RZ/A2 is almost the same as R-Car gen3, but
with some minor differences.

This looks good to me. So unless someone objects I intend to queue
this up for 4.21, once 4.20 rc1 is out. Or perhaps the clock patch
should go via the clock tree?
Thanks!

FYI,
I just tried to apply my patches to what is in -next.
It looks likes Fabrizio beat me to it (RZ/G1C has the same controller),
so there will be conflicts because we were both be modifying the same
lines in Kconfig and in the driver (adding the compatible strings).
It also looks like Fabrizio started using the name
"renesas,sdhi-mmc-xxxx" (as in, added the '-mmc'), but I'll probably
just keep mine the way it is (no '-mmc').
So if you don't feel like fixing it up, let me know and I'll send an update.
Chris
