There are no in-kernel users of the MVSDIO platform data method
(instantiating from a board file) so just delete this code and
make this a DT-only driver. We depend on OF and check that we have
an OF node in probe().

Looks good. I guess i would of reversed the order of these two patches
so you don't first add struct mvsdio_platform_data to the driver and
then remove it, but that is a minor nit pick.

Ulf can just squash them if he likes, that'd do it.

Thanks, applied for next!

I decided to keep the patches as is, because I think the split
provided an easy way to review the changes.

Kind regards
