[PATCH V5 0/3] scsi: ufs: Let devices remain runtime suspended during system suspend

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi

UFS devices can remain runtime suspended at system suspend time,
if the conditions are right.  Add support for that, first fixing
the impediments.

Changes in V5:

      scsi: ufs: Fix error handler clear ua deadlock
	Update commit message
	Try to abort REQUEST SENSE if it times out

Changes in V4:

      scsi: ufs: Fix error handler clear ua deadlock

	Do request-sense directly

Changes in V3:

      scsi: ufs: Fix error handler clear ua deadlock

	Correct commit message.
	Amend stable tags to add dependent cherry picks

Changes in V2:

    scsi: ufs: Let devices remain runtime suspended during system suspend

	The ufs-hisi driver uses different RPM and SPM, but it is made
	explicit by a new parameter to suspend prepare.
