When a card is removed while it is being accessed, a command can get stuck so
that no timeout or end of command interrupt ever occurs. The command getting
stuck is almost always CDM12, but also the other commands can get stuck. Catch

Use work queues for starting new commands instead of starting them
directly from irq handler. The command scheduling needs to be delayed
a bit for some cards which should not be done from an interrupt.

Hi Pierre, Tony and folks,
The patch series that follows is a synchronization of MMC OMAP driver
from Linux-OMAP tree into mainline tree.
Basically, it brings MMC multislot support for OMAP boards with one slot
(like H2 1611, H3 1710) or two slots (like H4 2420 and N800). Others

MMCA spec says the mmc clock should be kept running for at least
8 cycles after the last RW request. Ensure this with lazy clock

Hi Pierre,
Find in this series the pending patches from Linux-OMAP to mainline for
drivers/mmc/omap.c
The patches series was applied against Linus' tree 2.6.21-rc7-git6.
Anyway, it was tested on OMAP H2 (using omap_h2_1610_defconfig available
on linus' tree).
BR,
Carlos.
