[GIT PULL] MMC updates for 3.1-rc1.

Date: Thu Jul 21 2011 - 23:11:17 EST

Hi Linus,

Please pull from:

git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc.git for-linus

to receive MMC updates for 3.1. There are currently no merge conflicts,
and the patches have been tested in linux-next. Thanks.

Highlights are:

Core:
* New non-blocking request framework from Per Forlin for removing DMA
preparation overhead, used by adding pre_req() and post_req() driver
hooks for preparing DMA descriptors ahead of time as described in
Documentation/mmc/mmc-async-req.txt.

* Improved MMC error detection and recovery from Russell King.

Drivers:
* Fix errors with the Ricoh e823 controller (as found in ThinkPad X220,
Tecra R850, PortÃgà R830) by lowering its SD bus frequency to 50MHz.

* Runtime PM support for omap_hsmmc, tmio_mmc, and sh_mmcif.

* sdhci-pltfm architecture rework by Shawn Guo.

* Split up sdhci-pxa into independent sdhci-pxav2 (pxa910) and
sdhci-pxav3 (MMP2) drivers.

* Implement non-blocking framework hooks for the mmci driver.
