From 5301b7a04040b0a6191856c765146e0a9ab88ebc Mon Sep 17 00:00:00 2001 From: Can Guo Date: Sat, 2 Dec 2023 04:36:15 -0800 Subject: 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.
