MMC highlights for 3.12:

Browse source 
Core:
  - Support Allocation Units 8MB-64MB in SD3.0, previous max was 4MB.
  - The slot-gpio helper can now handle GPIO debouncing card-detect.
  - Read supported voltages from DT "voltage-ranges" property.
 
 Drivers:
  - dw_mmc: Add support for ARC architecture, and support exynos5420.
  - mmc_spi: Support CD/RO GPIOs.
  - sh_mobile_sdhi: Add compatibility for more Renesas SoCs.
  - sh_mmcif: Add DT support for DMA channels.
