This series of patches addresses some suspend/resume problems with
dw_mmc on exynos platforms.  Since suspend/resume is not fully working
on ToT Linux (3.10) on exynos5250-snow, this series was tested against
the current ToT ChromeOS 3.8 tree.  I have confirmed basic booting
and eMMC / SD card usage (and compiling, honest!) against ToT Linux.

Changes in v3:
- Add freeze/thaw and poweroff/restore noirq entries.

Changes in v2:
- Fix typo (some -> come)
- Use ~0 instead of 0xFFFFFFFF; add comment about value
- Use suspend_noirq as per James Hogan.

Doug Anderson (5):
  mmc: dw_mmc: Invalidate cache of current_speed after suspend/resume
  mmc: dw_mmc: Add suspend_noirq/resume_noirq callbacks for dw_mmc-pltfm
  mmc: dw_mmc: Add exynos resume_noirq callback to clear WAKEUP_INT
  mmc: dw_mmc: Always setup the bus after suspend/resume
  mmc: dw_mmc: Set timeout to max upon resume
