[PATCH v5 0/4] mmc: dw_mmc: fixes for suspend/resume on exynos

From: Doug Anderson
Date: Fri Aug 09 2013 - 12:33:36 EST

This series of patches addresses some suspend/resume problems with
dw_mmc on exynos platforms, espeically exynos5420. Since
suspend/resume is not fully working on ToT Linux (v3.11-rc4) 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.

I have received confirmation from Samsung that the problem solved is a
silicon errata on exynos5420 and that this is a good fix.

Changes in v5:
- Remove force_clkinit as per Jaehoon.
- Update commit message to (hopefully) be clearer.
- Cleaned up dw_mci_exynos_resume_noirq() comment as per Seungwon.
- Don't memcpy dev_pm_ops structure, define a new one.

Changes in v4:
- Take Seungwon's suggestion and don't add any dw_mmc-pltfm code.

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 (4):
mmc: dw_mmc: Invalidate cache of current_speed after suspend/resume
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
