Subject: [mmc] alternative TI FM MMC/SD driver for 2.6.21-rc7

Hi,

The device is present in many notebooks. Notebooks depend heavily on 
suspend/resume functionality. tifm_core/7xx1/sd family is an ambitous, 
but uncompleted project. It used to crash on resuming, or hang up on 
suspending. A less common failure used to be trigerred by a fast card 
insert/removal sequence. Finally, tifm_sd module needs to be manually 
inserted.

I have found it easier to rewrite the driver, than to fix. This driver 
is kind of mutant. The bones are taken from sdhci and omap, the meat - 
from tifm_*. It contains all features (and bugs except named above) of 
tifm_* as it was in kernel 2.6.21-rc7.

I have been testing this version since linux-2.6.18 (daily reading 
photos from cards, daily suspending/resuming) without a single glitch.

Alex Dubov has done exceptionally great lots of work to teach linux 
speak to TIFM. This is just a reorganization of his project.

The driver seems to be practically stable, but it definitely must be 
tested by more people. Please also report any issues with this driver to 
http://bugzilla.kernel.org/show_bug.cgi?id=8352 so that valuable info is 
not lost.

Best regards,
Sergey Yanovich
