Subject: [PATCH] scsi/ufs: qcom: Set phy mode based on the controllers HS MODE
Git-commit: e9dc42c70c003746f2b541114f1fa19dc0ab232d
Patch-mainline: v4.15-rc1
References: bsc#1118139
Set the phy mode based on the UFS HS PA mode. This lets the
controller let phy know the mode in which the PHY Adapter is
running and set the phy rates accordingly.
