Subject: [PATCH v2 04/15] phy: qcom-qmp-ufs: Add HS G4 mode support to SM8250 SoC
Date:   Mon, 31 Oct 2022 23:32:06 +0530

UFS PHY in SM8250 SoC is capable of operating at HS G4 mode. Hence, add the
required register settings using the tables_hs_g4 struct instance. This
also requires a separate qmp_phy_cfg for SM8250 instead of SM8150.
