Subject: [PATCH 04/15] phy: qcom-qmp-ufs: Add HS G4 mode support to SM8250 SoC
Date: Sat, 29 Oct 2022 19:46:22 +0530 [thread overview]
Message-ID: <20221029141633.295650-5-manivannan.sadhasivam@linaro.org> (raw)
In-Reply-To: <20221029141633.295650-1-manivannan.sadhasivam@linaro.org>
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.
