Subject[PATCH 0/5] mmc: core: Add support for graceful host removal for eMMC/SD
Date
As pointed out by Wolfram Sang and already discussed at LKML [1] - an mmc host
driver may allow to unbind from its corresponding host device. If there is and
eMMC/SD card attached to the host, the mmc core will just try to cut the power
for it, without trying to make a graceful power-off, thus potentially we could
damage the card.

This series intends to fix this problem for eMMC/SD cards.

Please help to test and review!

Kind regards
Ulf Hansson

Ulf Hansson (5):
mmc: core: Convert mmc_can_poweroff_notify() into a bool
mmc: core: Further avoid re-storing power to the eMMC before a
shutdown
mmc: core: Convert into an enum for the poweroff-type for eMMC
mmc: core: Add support for graceful host removal for eMMC
mmc: core: Add support for graceful host removal for SD
