Merge tag 'mmc-updates-for-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc

Pull MMC updates from Chris Ball:
 "MMC highlights for 3.15:

  Core:
   - CONFIG_MMC_UNSAFE_RESUME=y is now default behavior
   - DT bindings for SDHCI UHS, eMMC HS200, high-speed DDR, at 1.8/1.2V
   - Add GPIO descriptor based slot-gpio card detect API

  Drivers:
   - dw_mmc: Refactor SOCFPGA support as a variant inside dw_mmc-pltfm.c
   - mmci: Support HW busy detection on ux500
   - omap: Support MMC_ERASE
   - omap_hsmmc: Support MMC_PM_KEEP_POWER, MMC_PM_WAKE_SDIO_IRQ, (a)cmd23
   - rtsx: Support pre-req/post-req async
   - sdhci: Add support for Realtek RTS5250 controllers
   - sdhci-acpi: Add support for 80860F16, fix 80860F14/SDIO card detect
   - sdhci-msm: Add new driver for Qualcomm SDHCI chipset support
   - sdhci-pxav3: Add support for Marvell Armada 380 and 385 SoCs"
