Pull MMC update from Chris Ball:
 "MMC highlights for 3.16:

  Core:
   - support HS400 mode of eMMC 5.0, via DT bindings mmc-hs400-1_{2,8}v
   - if card init at 3.3v doesn't work, try 1.8v and 1.2v too

  Drivers:
   - moxart: New driver for MOXA ART SoCs
   - rtsx_usb_sdmmc: New driver for Realtek USB card readers
   - sdhci: Large rework around IRQ/regulator handling, remove card_tasklet
   - sdhci-pci-o2micro: Add SeaBird SeaEagle SD3 support
   - sunxi: New driver for Allwinner sunxi SoCs
   - usdhi6rol0: New driver for Renesas SD/SDIO controller"
