Hi Here is V2, now re-based on top of patch "scsi: ufs: sysfs:reworking of the rpm_lvl and spm_lvl entries". 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.
