Hi,

This is just resend of the patch with added mmc ML and dw-mmc maintainers.

Javier, I have no access to peach-pi(t) schematics, so I do not know if they
have mmc-cd line connected to gpc0-2 gpio, but I guess it could be the case.
You could check if similar patches will fix the issue for them.

Regards
Andrzej
