Merge tag 'mmc-v3.16-1' of git://git.linaro.org/people/ulf.hansson/mmc into next

Browse Source 
Pull MMC update from Ulf Hansson:
 "These patches are mainly updates for the mmci driver and have been
  tested in linux-next.

  Some ARM SoC related patches are also included and those have been
  acked from the corresponding maintainers to go through my mmc tree.

  Updates for mmci driver:
   - Put the device into low power state at system suspend.
   - Convert to the common mmc DT parser.
   - Add missing DT bindings needed for ux500.

  Updates for ARM ux500|u300:
   - Convert to the common mmc DT bindings.
   - Remove redundant board file for mmci platform data"
