    Subject[PATCH v6 0/3] mmc: dw_mmc: fixes for suspend/resume on exynos
    Date
    This series of patches addresses some suspend/resume problems with
    dw_mmc on exynos platforms, espeically exynos5420. This patchset was
    tested on the current ToT Chromeos 3.8 tree (which has lots of
    backports from 3.10/3.11) and on ToT Linux (v3.11-rc6). I have
    confirmed basic booting and that SD cards work across suspend/resume
    (both if they are plugged in and if they are not plugged in).

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

    Changes in v6:
    - Took out TODO comment copied from main platform code.
    - Replaces previous pathes that ensured saving/restoring clocks.

    Changes in v5:
    - 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:
    - Use suspend_noirq as per James Hogan.

    Doug Anderson (3):
    mmc: dw_mmc: Add exynos resume_noirq callback to clear WAKEUP_INT
    mmc: dw_mmc: Honor requests to set the clock to 0 (turn off clock)
    mmc: dw_mmc: Set timeout to max upon resume
