RE: [PATCH v4 4/5] scsi: ufs: Do not clear the DL layer timers

[Avri Altman]

> During power mode change, PACP_PWR_Req frame sends
> PAPowerModeUserData parameters (and they are considered valid by device if
> Flags[4] - UserDataValid bit is set in the same frame).
> Currently we don't set these PAPowerModeUserData parameters and hardware
> always sets UserDataValid bit which would clear all the DL layer timeout values
> of the peer device after the power mode change.
> 
> This change sets the PAPowerModeUserData[0..5] to UniPro specification
> recommended default values, in addition we are also setting the relevant
> DME_LOCAL_* timer attributes as required by UFS HCI specification.
