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 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 drivers/mmc/host/dw_mmc-exynos.c | 51 ++++++++++++++++++++++++++++++++++++++-- drivers/mmc/host/dw_mmc.c | 15 ++++++++---- 2 files changed, 60 insertions(+), 6 deletions(-) -- 1.8.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
