Subject: [PATCH v9 1/2] phy: qualcomm: phy-qcom-qmp-ufs: Rectify SM8550 UFS HS-G4 PHY Settings
The registers, which are being touched in current SM8550 UFS PHY settings,
and the values being programmed are mainly the ones working for HS-G4 mode,
meanwhile, there are also a few ones somehow taken from HS-G5 PHY settings.
However, even consider HS-G4 mode only, some of them are incorrect and some
are missing. Rectify the HS-G4 PHY settings by strictly aligning with the
SM8550 UFS PHY Hardware Programming Guide suggested HS-G4 PHY settings.
Fixes: 1679bfef906f ("phy: qcom-qmp-ufs: Add SM8550 support")
