[PATCH V1] phy: qcom-qmp-ufs: check for mode type for phy setting
From: Nitin Rawat
Date: Mon Apr 07 2025 - 08:10:41 EST
Generally all target supports Rate B but for very few like SM8550,
two sets of UFS PHY settings are provided, one set is to support
HS-G5 Rate A and another set is to support HS-G4 and lower
gears with Rate B.
Commit b02cc9a17679("phy: qcom-qmp-ufs: Add PHY Configuration support
for sm8750") apply Rate B setting for SM8550 gear 5 without checking
for mode value (Rate A or Rate B) from Controller driver which caused
issue as SM8550 support rate A for Gear 5.
Fix this by adding mode check before applying Rat B phy setting.
