[PATCH 0/3] [Q/master] omap3: mmc and ehci fixes

BugLink: http://bugs.launchpad.net/bugs/1017717

Patch 1 is a revert of PM related commit that killed usb on Beagle boards - 
	see http://permalink.gmane.org/gmane.linux.usb.general/66239.
Patch 2 disables generic ehci hdc code (USB_EHCI_HCD_PLATFORM) since we
	already compile-in platform/arch specific code (USB_EHCI_HCD_OMAP).

BugLink: http://bugs.launchpad.net/bugs/1017718

Patch 3 is a revert of an mmc-related commit that caused severe filesystem
	corruption - see https://lkml.org/lkml/2012/6/10/225.

None of the aforementioned patches are upstream yet, but they will be in one
of the next rc (see the respective discussions linked in the lp bugs).

With these 3 patches, omap3 kernel in Q is back in a good shape.

[PATCH 3/3] UBUNTU: SAUCE: Revert "mmc: omap_hsmmc: Enable Auto CMD12"

From: Ming Lei <ming.lei <at> canonical.com>

BugLink: http://bugs.launchpad.net/bugs/1017717

This patch reverts the commit dba3c29ea4a1d5d544.

After bisecting, this commit dba3c29 is found to ruin micro-SD card data
(writing incorrect file, or fs is corrupt after several times mount)
on the beagle-xm revB, and reverting the commit will fix the problem.

Also from TRM of OMAP3/OMAP4/DM37x, the below is mentioned about
the Auto CMD12 Enable bit.
        - SDIO does not support this feature.
        - SD card only.
Looks it is not suitable to always enable Auto CMD12 in host controller
driver.

Considered that the commit is not mature enough, so ask to revert it
first.
