Subject: [PATCH v2 4/5] scsi/ufs: qcom: Set phy mode based on the controllers HS MODE
Date: Thu, 12 Oct 2017 11:49:35 +0530 [thread overview]
Message-ID: <1507789176-2760-5-git-send-email-vivek.gautam@codeaurora.org> (raw)
In-Reply-To: <1507789176-2760-1-git-send-email-vivek.gautam@codeaurora.org>
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.
