What: /sys/bus/*/drivers/ufshcd/*/auto_hibern8 Date: March 2018 Contact: linux-scsi@vger.kernel.org Description: This file contains the auto-hibernate idle timer setting of a UFS host controller. A value of '0' means auto-hibernate is not enabled. Otherwise the value is the number of microseconds of idle time before the UFS host controller will autonomously put the link into hibernate state. That will save power at the expense of increased latency. Note that the hardware supports 10-bit values with a power-of-ten multiplier which allows a maximum value of 102300000. Refer to the UFS Host Controller Interface specification for more details.
