Noted, I'll send a non-RFC version of the patchset very soon!

I might have overpromised on this one :( I've already tried to limit the
scope of the patchset to be as small as possible while still being
meaningful and my goal was to add the SDIO driver to give the full
picture of what we're trying to achieve. I'll see if I can cut it down
even further.


Side note for list administrators: I can send patchset just fine with
git-send-email but posting to the list with my email client (aerc) gives
me every single time:

        The message is being held because:

            Message has implicit destination

I'm subscribed to the list and my emails seem to make it in the end (I
don't know if they are manually released or not). I looked up that error
message and I didn't find anything useful. Am I the only one having that
issue? Would be happy to find a solution.


Thank you,
