Ah, sorry Fabio. I indeed understood you wrong and thanks Stefan for clarifying.
I have the new message in for v3.

I guess what Fabio meant here is explain this patch.

The commit message really could be improved, e.g.:

Add pinmuxing and do not specify voltage restrictions for the usdhc
instance
available on the modules edge connector. This allows to use SD-cards
with
higher transfer modes if supported by the carrier board.

This commit is in preparation of another patch that didn't made into this
patchset (downstream stuff in there). But I will do another patch on top that
will use this patch here. That should anyway be in mainline.

It would be nice to explain the reason for doing this.

You add the entries for 100MHz and 200MHz, but I don't see them being
referenced anywhere.
