Merge tag 'mmc-merge-for-3.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

Pull MMC updates from Chris Ball:
 "Core:
   - Add DT properties for card detection (broken-cd, cd-gpios,
     non-removable)
   - Don't poll non-removable devices
   - Fixup/rework eMMC sleep mode/"power off notify" feature
   - Support eMMC background operations (BKOPS).  To set the one-time
     programmable fuse that enables bkops on an eMMC that doesn't
     already have it set, you can use the "mmc bkops enable" command in:

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

  Drivers:
   - atmel-mci, dw_mmc, pxa-mci, dove, s3c, spear: Add device tree
     support
   - bfin_sdh: Add support for the controller in bf60x
   - dw_mmc: Support Samsung Exynos SoCs
   - eSDHC: Add ADMA support
   - sdhci: Support testing a cd-gpio (from slot-gpio) instead of
     presence bit
   - sdhci-pltfm: Support broken-cd DT property
   - tegra: Convert to only supporting DT (mach-tegra has gone DT-only)"
