Linus Torvalds 2dfea3803d This is the MFD patch set for the 3.8 merge window.
We have several new drivers, most of the time coming with their sub devices
 drivers:
 
 - Austria Microsystem's AS3711
 - Nano River's viperboard
 - TI's TPS80031, AM335x TS/ADC,
 - Realtek's MMC/memstick card reader
 - Nokia's retu
 
 We also got some notable cleanups and improvements:
 
 - tps6586x got converted to IRQ domains.
 - tps65910 and tps65090 moved to the regmap IRQ API.
 - STMPE is now Device Tree aware.
 - A general twl6040 and twl-core cleanup, with moves to the regmap I/O and IRQ
   APIs and a conversion to the recently added PWM framework.
 - sta2x11 gained regmap support.
 
 Then the rest is mostly tiny cleanups and fixes, among which we have Mark's
 wm5xxx and wm8xxx patchset.

Far amount of annoying but largely trivial conflicts.  Many due to
__devinit/exit removal, others due to one or two of the new drivers also
having come in through another tree.

Linus Torvalds 6a5971d8fe Char/Misc driver merge for 3.8-rc1
Here is the "big" char/misc driver patches for 3.8-rc1.  I'm starting to
 put random driver subsystems that I had previously sent you through the
 driver-core tree in this tree, as it makes more sense to do so.
 
 Nothing major here, the various __dev* removals, some mei driver
 updates, and other random driver-specific things from the different
 maintainers and developers.
 
 Note, some MFD drivers got added through this tree, and they are also
 coming in through the "real" MFD tree as well, due to some major
 mis-communication between me and the different developers.  If you have
 any merge conflicts, take the ones from the MFD tree, not these ones,
 sorry about that.
 
 All of this has been in linux-next for a while.

Sascha Hauer 6187fee46f mmc: remove imxmmc driver
This driver is broken since 2.6.31 when the traditional i.MX1
support was removed.

In theory the i.MX1 mmc controller can be supported by the mxcmmc
driver which basically is the same hardware. However, the i.MX1
controller has severe bugs which made several workarounds necessary which
resulted in a different driver structure. At that time it seemed easier
to write a second driver to support hardware without bugs.

As noone cared for the i.MX1 driver for a long time and it does
not compile, remove it.

Shawn Guo f0de836923 mmc: sdhci: change sdhci-pltfm into a module
There are a couple of problems left from the sdhci pltfm and OF
consolidation changes.

* When building more than one sdhci-pltfm based drivers in the same
  image, linker will give multiple definition error on the sdhci-pltfm
  helper functions.  For example right now, building sdhci-of-esdhc
  and sdhci-of-hlwd together is a valid combination from Kconfig view.

* With the current build method, there is error with building the
  drivers as module, but module installation fails with modprobe.

The patch fixes above problems by changing sdhci-pltfm into a module.
To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves
these accessors into sdhci-pltfm.h as the 'static inline' functions.
As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in
turn can be removed from individual drivers which already include
sdhci-pltfm.h.

The patch turns the sdhci-of-core common stuff into helper functions
added into sdhci-pltfm.c, and makes sdhci-of device drviers self
registered using the same pair of .probe and .remove used by
sdhci-pltfm device drivers.

As a result, sdhci-of-core.c and sdhci-of.h can be eliminated with
those common things merged into sdhci-pltfm.c and sdhci-pltfm.h
respectively.

Guennadi Liakhovetski 42051e8a7b mmc: tmio: convert the SDHI MMC driver from MFD to a platform driver
On sh-mobile platforms the SDHI driver was using the tmio_mmc SD/SDIO
MFD cell driver. Now that the tmio_mmc driver has been split into a
core and a separate MFD glue, we can support SDHI natively without the
need to emulate an MFD controller. This also allows to support systems
with an on-SoC SDHI controller and a separate MFD with a TMIO core.

Guennadi Liakhovetski b6147490e6 mmc: tmio: split core functionality, DMA and MFD glue
TMIO MMC chips contain an SD / SDIO IP core from Panasonic, similar to
the one, used in MN5774 and other MN57xx controllers. These IP cores are
included in many multifunction devices, in sh-mobile chips from Renesas,
in the latter case they can also use DMA. Some sh-mobile implementations
also have some other specialities, that MFD-based solutions don't have.
This makes supporting all these features in a monolithic driver inconveniet
and error-prone. This patch splits the driver into 3 parts: the core,
the MFD glue and the DMA support. In case of a modular build, two modules
will be built: mmc_tmio_core and mmc_tmio.

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.

Maxim Levitsky 03cd8f7ebe ricoh_mmc: port from driver to pci quirk
This patch solves nasty problem original driver has.

Original goal of the ricoh_mmc was to disable this device because then,
mmc cards can be read using standard SDHCI controller, thus avoiding
writing of yet another driver.

However, the act of disablement, makes other pci functions that belong to
this controller (xD and memstick) shift up one level, thus pci core has
now wrong idea about these devices.

To fix this issue, this patch moves the driver into the pci quirk section,
thus it is executes before the pci is enumerated, and therefore solving
that issue, also same sequence of commands is performed on resume for same
reasons.

Also regardless of the above, this way is cleaner.  You still need to set
CONFIG_MMC_RICOH_MMC to enable this quirk
