From: Ulf Hansson <ulf.hans...@linaro.org> SDIO has been using runtime pm for a while to handle runtime power save operations. This patchset is enabling the option to make the sd/mmc blockdevices to use runtime pm as well.
The runtime pm implementation for the block device will make use of autosuspend to defer power save operation to after request inactivty for a certain time. To actually perform some power save operations the corresponding bus ops for mmc and sd shall be implemented. Typically it could make sense to do BKOPS for eMMC in here. Ulf Hansson (3): mmc: core: Remove power_restore bus_ops for mmc and sd mmc: core: Add bus_ops for runtime pm callbacks mmc: block: Enable runtime pm for mmc blkdevice drivers/mmc/card/block.c | 28 ++++++++++++++++++++++++++-- drivers/mmc/core/bus.c | 14 ++++++++++++-- drivers/mmc/core/core.h | 2 ++ drivers/mmc/core/mmc.c | 14 -------------- drivers/mmc/core/sd.c | 14 -------------- drivers/mmc/core/sdio.c | 20 ++++++++++++++++++++ 6 files changed, 60 insertions(+), 32 deletions(-) -- 1.7.10 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
