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.
