Merge tag 'mmc-merge-for-3.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

Pull MMC updates from Chris Ball:
 "MMC highlights for 3.6:

  Core:
   - Rename cd-gpio to slot-gpio and extend it to support more slot GPIO
     functions, such as write-protect.
   - Add a function to get regulators (Vdd and Vccq) for a host.

  Drivers:
   - sdhci-pxav2, sdhci-pxav3: Add device tree support.
   - sdhi: Add device tree support.
   - sh_mmcif: Add support for regulators, device tree, slot-gpio.
   - tmio: Add regulator support, use slot-gpio."
