c4512f79dc sdhci: add auto CMD12 support for eSDHC driver
Add auto CMD12 command support for eSDHC driver.  This is needed by P4080
and P1022 for block read/write.  Manual asynchronous CMD12 abort operation
causes protocol violations on these silicons.

17866e14f3 sdhci-s3c: add support for new card detection methods
On some Samsung SoCs not all SDHCI controllers have card detect (CD) line.
 For some embedded designs it is not even needed, because ususally the
device (like SDIO flash memory or wifi controller) is permanently wired to
the controller.  There are also systems which have a card detect line
connected to some of the external interrupt lines or the presence of the
card depends on some other actions (like enabling a power regulator).

This patch adds support for all these cases.  The following card detection
methods are possible:

1. internal sdhci host card detect line
2. external event
3. external gpio interrupt
4. no card detect line, controller will poll for the card
5. no card detect line, card is permanently wired to the controller
(once detected host won't poll it any more)

By default, all existing code would use method #1, what is compatible with
the previous version of the driver.

In case of external event, two callbacks must be provided in platdata:
ext_cd_init and ext_cd_cleanup.  Both of them get a callback to a function
that notifies the s3c-sdhci host contoller as their argument.  That
callback function should be called from the even dispatcher to let host
notice the card insertion/removal.

In case of external gpio interrupt, a gpio pin number must be provided in
platdata (ext_cd_gpio parameter), as well as the information about the
polarity of that gpio pin (ext_cd_gpio_invert).  By default
(ext_cd_gpio_invert == 0) gpio value 0 means 'card has been removed', but
this can be changed to 'card has been removed' when ext_cd_gpio_invert ==
1.

This patch adds all required changes to sdhci-s3c driver.

ce5f036bbb sdhci-s3c: add support for the non standard minimal clock value
S3C SDHCI host controller can change the source for generating mmc clock.
By default host bus clock is used, what causes some problems on machines
with 133MHz bus, because the SDHCI divider cannot be as high get proper
clock value for identification mode.  This is not a problem for the
controller, because it can generate lower frequencies from other clock
sources.  This patch changes sdhci driver to use get_min_clock() call if
it has been provided.

This fixes the flood of the following warnings on Samsung S5PV210 SoCs:
mmc0: Minimum clock frequency too high for identification mode

6f51be3d37 sdio: allow non-standard SDIO cards
There are some chips (like TI WL12xx series) that can be interfaced over
SDIO but don't support the SDIO specification, meaning that they are
missing CIA (Common I/O Area) with all it's registers.  Current Linux SDIO
implementation relies on those registers to identify and configure the
card, so non-standard cards can not function and cause lots of warnings
from the core when it reads invalid data from non-existent registers.

After this patch, init_card() host callback can now set new quirk
MMC_QUIRK_NONSTD_SDIO, which means that SDIO core should not try to access
any standard SDIO registers and rely on init_card() to fill all SDIO
structures instead.  As those cards are usually embedded chips, all the
required information can be obtained from machine board files by the host
driver when it's called through init_card() callback.

845e3f4f06 sdhci-pltfm: reorganize Makefile entries to support SoC devices
Due to build system limitations, intermediate and final objects can't have
the same names.  And as we're going to start building SoC-specific
objects, let's rename the module to sdhci-platform, into which we'll link
sdhci-pltfm and SoC-specifc objects.

There should be no issue in renaming as the driver uses modalias
mechanism.

This is exactly the same approach as in sdhci-of driver.

27151dc9e3 mmc: omap: fix for bus width which improves SD card's peformance.
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.

ccc92c2324 mmc: make sdhci work with ricoh mmc controller
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

4c2ef25fe0 mmc: fix all hangs related to mmc/sd card insert/removal during suspend/resume
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.

71578a1eaa mmc: split mmc_sd_init_card()
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.

6e9624b8ca block: push down BKL into .open and .release
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.

74bc80931c ARM: Fix Versatile/Realview/VExpress MMC card detection sense
The MMC card detection sense has become really confused with negations
at various levels, leading to some platforms not detecting inserted
cards.  Fix this by converting everything to positive logic throughout,
thereby getting rid of these negations.

ac8b422838 pcmcia: remove cs_types.h
Remove cs_types.h which is no longer needed: Most definitions aren't
used at all, a few can be made away with, and two remaining definitions
(typedefs, unfortunatley) may be moved to more specific places.

Although both the U300 and Ux500 use ST variants, the HWFCEN bits are at
different positions, so use the variant_data to store the information.

Add a variant_data structure to handle the differences between the
various variants of this peripheral.  Add a first quirk for a default
MCICLOCK value, required on the Ux500 variant where the enable bit needs
to be always set, since it controls access to some registers.

f5e2574e73 ARM: 6239/1: mmci: let core poll for card detection
Use the MMC core's ability to poll for card detection.  This also has
the advantage of doing the gpio_get_value from a workqueue instead of
timer, allowing the gpio to be on a sleeping gpiochip.

4ce1d6cbf0 ARM: 6237/1: mmci: use sg_miter API to fix multi-page sg handling
The mmci driver's SG list iteration logic assumes that each SG entry
spans only one page, and only maps and flushes one page of the sg.  This
is not a valid assumption.  Fix it by converting the driver to the
sg_miter API, which correctly handles sgs which span multiple pages.
