Subject: [PATCH V3 1/9] scsi: ufs: qcom: add a new phy calibrate API call
Date: Thu, 10 Apr 2025 14:30:54 +0530	[thread overview]
Message-ID: <20250410090102.20781-2-quic_nitirawa@quicinc.com> (raw)
In-Reply-To: <20250410090102.20781-1-quic_nitirawa@quicinc.com>

Introduce a new phy calibrate API call in the UFS Qualcomm driver to
separate phy calibration from phy power-on. This change is a precursor
to the next patchset in this series, which requires these two operations
to be distinct.
