Michał Potomski has previously sent a patch for Auto-Hibernate, but this patch is slightly different, based on the latest ufs-sysfs changes, it also takes care to restore auto-hibernate during resume, and otherwise avoids updating the register if the device is runtime suspended. Also a default value of 150ms is set. Changes in V3: Return -EOPNOTSUPP from auto_hibern8_show() if Auto-Hibernate is not supported. Changes in V2: Re-based on top of (yet to be applied) patch "scsi: ufs: sysfs: reworking of the rpm_lvl and spm_lvl entries" Adrian Hunter (1): scsi: ufs: Add support for Auto-Hibernate Idle Timer Documentation/ABI/testing/sysfs-driver-ufs | 15 ++++++ drivers/scsi/ufs/ufs-sysfs.c | 77 ++++++++++++++++++++++++++++++ drivers/scsi/ufs/ufshcd.c | 26 ++++++++++ drivers/scsi/ufs/ufshcd.h | 3 ++ drivers/scsi/ufs/ufshci.h | 7 +++ 5 files changed, 128 insertions(+) Regards Adrian
