Sometimes want to place SoC-specific parts alongside with the generic
driver, and to do so, we have to switch the driver over to the module
device table matching.
Note that drivers/mmc/host/sdhci-pltfm.h is so far empty, but it'll hold
SoC-specific driver data handlers soon.

This patch improves low speeds for SD cards.
OMAP-MMC controller's can support maximum bus width of '8'. when bus
width is mentioned as "8" in controller data,the SD stack will check
whether bus width is "4" and if not it will set bus width to "1" and there
by degrading performance. This patch fixes the issue and improves the
performance of SD cards.

The current way of disabling it is not well tested by vendor and has all
kinds of bugs that show up on resume from ram/disk. A very good example
is a dead SDHCI controller.
Old way of disabling is still supported by continuing to use
CONFIG_MMC_RICOH_MMC.
Based on 'http://list.drzeus.cx/pipermail/sdhci-devel/2007-December/002085.html'
Therefore most of the credit for this goes to Andrew de Quincey

If you don't use CONFIG_MMC_UNSAFE_RESUME, as soon as you attempt to
suspend, the card will be removed, therefore this patch doesn't change the
behavior of this option.
However the removal will be done by pm notifier, which runs while
userspace is still not frozen and thus can freely use del_gendisk, without
the risk of deadlock which would happen otherwise.
Card detect workqueue is now disabled while userspace is frozen, Therefore
if you do use CONFIG_MMC_UNSAFE_RESUME, and remove the card during
suspend, the removal will be detected as soon as userspace is unfrozen,
again at the moment it is safe to call del_gendisk.
Tested with and without CONFIG_MMC_UNSAFE_RESUME with suspend and hibernate.

This series adds support for SD combo cards to MMC/SD driver stack.
SD combo consists of SD memory and SDIO parts in one package. Since the
parts have a separate SD command sets, after initialization, they can be
treated as independent cards on one bus.
Changes are divided into two patches. First is just moving initialization
code around so that SD memory part init can be called from SDIO init.
Second patch is a proper change enabling SD memory along SDIO. I tried to
move as much no-op changes to the first patch so that it's easier to
follow the required changes to initialization flow for SDIO cards.
This is based on Simplified SDIO spec v.2.00. The init sequence is
slightly modified to follow current SD memory init implementation.
Command sequences, assuming SD memory and SDIO indeed ignore unknown
commands, are the same as before for both parts.
This patch:
Prepare for SD-combo (IO+mem) support by splitting SD memory
card init and related functions.

The open and release block_device_operations are currently
called with the BKL held. In order to change that, we must
first make sure that all drivers that currently rely
on this have no regressions.
This blindly pushes the BKL into all .open and .release
operations for all block drivers to prepare for the
next step. The drivers can subsequently replace the BKL
with their own locks or remove it completely when it can
be shown that it is not needed.
The functions blkdev_get and blkdev_put are the only
remaining users of the big kernel lock in the block
layer, besides a few uses in the ioctl code, none
of which need to serialize with blkdev_{get,put}.
Most of these two functions is also under the protection
of bdev->bd_mutex, including the actual calls to
->open and ->release, and the common code does not
access any global data structures that need the BKL.

This patch tightens up the behaviour of of_modalias_node() to be more
predicatable and to eliminate the explicit of_modalias_tablep[] that
is currently used to override the first entry in the compatible list
of a device. The override table was needed originally because spi
and i2c drivers had no way to do of-style matching. Now that all
devices can have an of_node pointer, and all drivers can have an
of_match_table, the explicit override table is no longer needed
because each driver can specify its own OF-style match data.
The mpc8349emitx-mcu driver is modified to explicitly specify the
correct device to bind against.

Remove a BUG_ON for when interrupts are disabled during an MMC request.
During boot, interrupts can be disabled when a request is made, causing
this bug to be triggered. In reality, there's no reason this should halt
the kernel, as the driver has proved reliable in spite of disabled
interrupts, and additionally, there's nothing in this code that would
require interrupts to be enabled.
The only setup I've managed to make it trigger on is on the HTC Herald
during bootup when the driver is built into the kernel (mostly because
that's all I have). I believe it's related to the fact that on bootup I
get many timeout errors on "CMD5" while initializing the card. Each CMD5
timeout triggers that bug (I changed it to a WARN_ON to get it to boot in)
due to the fact that part of the timeout code involves sending the request
again. With interrupts turned off, that BUG would be triggered.

Update the MMCIF driver to include register information
and register access functions in the header file.
The MMCIF boot code builds on top of this.
