Subject: [PATCH v7 0/3] mmc: dw_mmc: fixes for suspend/resume on exynos
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 v7:
- Avoid printing the same clock over and over again w/ MMC_CLKGATE.
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
