Had you had the time to look at the issue?

I have looked at the issue, but not manage to cook some patches
for it.

However, it's on my top of my TODO list for mmc. No promises, but
perhaps and hopefully I manage to get something posted during the
coming release cycle.

I would be interested in a ESP8089 driver in mainline and that's why I want to pick up this discussion.

What is the current status of the "mmc_reprobe_device" implementation, that Hans was explaining and Ulf wanted to provide some months ago?

Ulf did eventually write a new way to deal with this and then Quentin
did manage to get the esp8089 driver to work with it, the new function
to use for this is added by this commit:

I'm not sure what the status of upstreaming the ep8089 driver is now
that we've this in place.

Quentin, do you have a version of the esp8089 driver somewhere
which will work correctly with the new mmc_sw_reset() function?

Also what is the status of adding this driver to say staging?

IIRC, we tried to get it into staging, and we got told that it was too
nice for staging at this point. So we're basically stuck somewhere
between staging and !staging, with the driver being too nice for the
former, and not nice enough for the latter :)

Ok, and is there someone willing to continue upstreaming the driver? Maybe someone can rebase and resend the latest approach?

After all it looks like a lot of work has already been done.
