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. + What: /sys/bus/platform/drivers/ufshcd/*/device_descriptor/device_type Date: February 2018 Contact: Stanislav Nijnikov <stanislav.nijnikov@wdc.com> |
