Thanks Ulf.
I will go over the new patch and will develop the periodic BKOPS on top of
it.

Thanks,
Maya

Subject: [PATCH 0/3] mmc: Use runtime pm for blkdevice

From: Ulf Hansson <ulf.hansson@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
