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.
Changes in v2:
- Removed the stated patch below from this patchset. It can be handled
separately. "mmc: core: Remove power_restore bus_ops for mmc and sd"
- Rebased patches on latest mmc-next.
- Added Acks.
Ulf Hansson (2):
mmc: core: Add bus_ops for runtime pm callbacks
mmc: block: Enable runtime pm for mmc blkdevice
