Pull MMC updates from Ulf Hansson:
 "MMC core:
   - Fix a race condition in the request handling
   - Skip trim commands for some buggy kingston eMMCs
   - An optimization and a correction for erase groups
   - Set CMD23 quirk for some Sandisk cards

  MMC host:
   - sdhci: Give GPIO CD higher precedence and don't poll when it's used
   - sdhci: Fix DMA memory leakage
   - sdhci: Some updates for clock management
   - sdhci-of-at91: introduce driver for the Atmel SDMMC
   - sdhci-of-arasan: Add support for sdhci-5.1
   - sdhci-esdhc-imx: Add support for imx7d which also supports HS400
   - sdhci: A collection of fixes and improvements for various sdhci hosts
   - omap_hsmmc: Modernization of the regulator code
   - dw_mmc: A couple of fixes for DMA and PIO mode
   - usdhi6rol0: A few fixes and support probe deferral for regulators
   - pxamci: Convert to use dmaengine
   - sh_mmcif: Fix the suspend process in a short term solution
   - tmio: Adjust timeout for commands
   - sunxi: Fix timeout while gating/ungating clock"
