MMC highlights for 3.11:

Browse source 
Core:
  - Add support for eMMC 5.1 devices.
  - Add MMC_CAP_AGGRESSIVE_PM capability for aggressive power management
    of eMMC/SD between requests, using runtime PM.
  - Add an ioctl to perform the eMMC 4.5 Sanitize command; sample code at:
    git://git.kernel.org/pub/scm/linux/kernel/git/cjb/mmc-utils.git
 
 Drivers:
  - dw_mmc: Add support for Rockchip's Cortex-A9 SoCs.
  - dw_mmc: Add support for Altera SoCFPGAs.
  - sdhci-esdhc-imx: Add support for 8-bit bus width, non-removable cards.
  - sdhci-bcm-kona: New driver for Broadcom Kona (281xx) SoCs.
  - sdhi/tmio: Add DT DMA support.
