Pull MMC update from Chris Ball:
 "MMC highlights for 3.10:

  Core:
   - Introduce MMC_CAP2_NO_PRESCAN_POWERUP to allow skipping
     mmc_power_up() at boot/initialization time if it's already
     happened, for performance (faster boot time) reasons.
   - Fix a bit width test failure that resulted in old eMMC cards being
     put into 1-bit mode when 4-bit mode was available.
   - Expose fwrev/hwrev for MMCv4 parts.
   - Improve card removal logic in the case where the card's removed
     slowly; we were missing card removal events if the card retained
     contact with the slot pads for long enough to reply to a CMD13
     while being removed.

  Drivers:
   - davinci_mmc: Support using PIO instead of DMA.
   - dw_mmc: Add support for Exynos4412.
   - mxcmmc: DT support, use slot-gpio API.
   - mxs-mmc: Add broken-cd/cd-inverted/non-removable DT property
     support.
   - sdhci-sirf: New sdhci-pltfm driver for CSR SiRF SoCs:
       SiRFprimaII: unicore ARM Cortex-A9
       SiRFatlas6: unicore ARM Cortex-A9
       SiRFmarco: dual core ARM Cortex-A9 SMP
   - sdhci-tegra: Add support for Tegra114 platforms, use
     mmc_of_parse()"
