Pull MMC updates from Ulf Hansson:
 "MMC core:
      - Fix ABI regression of MMC BLK ioctl
      - Remove the unused MMC_DATA_STREAM flag
      - Enable asynchronous system PM for the host device
      - Minor fixes and clean-ups

  SDHCI host:
     Throughout the years, the numbers of SDHCI variants have increased
     and so has also the numbers of SDHCI callbacks/quirks.  The purpose
     of these callbacks/quirks were to enable SDHCI to deal with variant
     specific requirements, but unfortunate this method didn't scale.
     Instead we have ended up with a mess.  Not only did the code become
     suboptimal but also highly fragile.

     Lately many discussions of how to move forward with SDHCI has taken
     place at the MMC mailing list.  Step by step, we aim to turn
     SDHCI's common code into a set of library functions.  This will
     enable for optimizations and allow some of the existing callbacks
     and quirks to be removed, which also should help to make the code
     less fragile.

     Therefore I am also really pleased to announce that Adrian Hunter
     (Intel) has volunteered to step in as the maintainer for SDHCI.

     Future wise, I hope the community around SDHCI will continue to
     grow and that this release cycle can be the starting point of
     moving SDHCI into a better shape.  As a matter of fact, already in
     this cycle the re-factoring has begun, but of course there are also
     fixes and new features included.  Some highlights:

      - sdhci-iproc: Add support for Broadcom's BCM2835 eMMC IP
      - sdhci-acpi: Add support for QCOM controllers
      - sdhci-pic32: Add new SDHCI variant for PIC32MZDA

  Other hosts:
      - atmel-mci: Fix a NULL pointer dereference
      - mediatek: Add SD write-protect support
      - mmc_spi: Fix card detect in GPIO case
      - tmio/sdhi: Add r8a7795 support
      - tmio/sdhi: Some fixes and clean-ups
      - dw_mmc: Add HW reset support
      - dw_mmc: Some fixes and clean-ups
      - sunxi: Add support for MMC DDR52 mode"
