Subject: [RFC] Orphaning MMC host drivers

I've reached the point where I've grown tired of trying to figure out who has
hardware for what. I intend to commit the following in a few days so if you care
about the quality of the drivers it's time to step up to the plate.

There's a rather long list of cc here, but I've included everyone that has been
involved in the drivers in one way or another in case one or two maintainers can
actually be found.

Even if you don't feel like maintaining this, feel free to suggest mailing lists
that should be added to the entries.

Hello Pierre,

as I have already stated, I would take responsibility
for I.MX SDHC driver. It is not perfect, but I am trying
to keep and fix it and I would be happy to receive
feedback or help from others.

The actual state is such, that read works for both SD/MMC,
but write is failing. The write path is timing sensitive
and some other kernel changes above 2.6.18 exposes these
problems. I have some ideas, how to dig for this problem
in mind, but I did not find time to try them yet.

I have already proposed MAINTAINERS change, but you
did not liked to point L: field to "sdhci-devel" list.
I propose ALKML mailing list this time as you suggested.

Do you include change or should I send my own patch
for review? Would you suggest change in driver name
to MOTOROLA I.MX MMCI DRIVER ?

Best wishes

Pavel

My original proposal with L: changed to ALKML

Great.

I'll included it in my end.

As for the name, I think it's easier for people to find stuff if the vendor name
is included. I'll take your name (which is more detailed) and stick a MOTOROLA
in the front.

Hi Pierre,

Carlos Aguiar and Anderson Briglia are interested in making sure the driver works for existing boards as they have access to them, and I can make it work for new omaps (2430, 3430).
