This patch fixes error:
drivers/mmc/host/omap.c: In function 'mmc_omap_get_dma_channel':
drivers/mmc/host/omap.c:1038: error: called object 'dev_name' is not a functionCommit 06916639e2fed9ee475efef2747a1b7429f8fe76 adds a function
called dev_name. This will cause a name conflict as dev_dbg calls
dev_name(((host->mmc)->parent)).This same issue should not affect other drivers as they don't seem
to use dev_name with dev_dbg.Thanks to Paul Walmsley for figuring this one out.

This fixes some two minor clk issues.
The first is a comparison where a byte will probably wrap around to 0 instead of being saturated to 255, shouldn't be triggered very often but need fixing.
The second is an attempt by the driver to adjust MCLK down to the maximum frequency according to the spec, so we don't accidentally overclock the PL18x block. None of the mach-{versatile|integrator|lh7a40x} that use it in-tree seem to have a problem with this (all are well below 100MHz, typically 33MHz), but some day there will be a problem.
This is not applied on top of the earlier mmci patch for race condition but rather a clean 2.6.25, but I guess it applies without major protests anyway.

Updated version of 4446/1. This also drops the suggested comparison
of host_remain for == 0, since that doesn't make sense (still works
for us, too). We have verified that this patch solve race problems
on atleast 2 archs at high frequencies.(Verbatim copy of old patch text below.)
The patch below fixes a race condition in the ARM MMCI PL18x driver.
If new data arrives in the FIFO while existing data is being read then
we get a second iteration of the loop in mmci_pio_read.However host->size is not updated until after mmci_pio_read returns,
so we get count = number of new bytes PLUS number of bytes already
copied in the first iteration. This results in a FIFO underrun as
we try and read mode data than is available.The fix is to compensating for data read on previous iterations
when calculating the amount of data in the FIFO.Signed-off-by: Linus Walleij

The limit was a fixed 100k limit in the busy loop, which is not
accurate. It would better to have time limit for the worst case
which occurs when sending 80 cycles at 400 kHz and takes about

for some 250 microseconds.Signed-off-by: Jarkko Lavinen

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
a stuck command with a timer and try sending the initialization stream until
the controller starts running again and responds with the end of command
status.Signed-off-by: Jarkko Lavinen

Suppressing uevents turned out to be a bad idea as it screws up the
order of events, making user space very confused. Change the system to
use sysfs groups instead.This is a regression that, for some odd reason, has gone unnoticed for
some time. It confuses hal so that the block devices (which have the
mmc device as a parent) are not registered. End result being that
desktop magic when cards are inserted won't work.Signed-off-by: Pierre Ossman
