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.
