[PATCH 6.8 155/715] arm64: dts: qcom: qcm2290: declare VLS CLAMP register for USB3 PHY

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Dmitry Baryshkov <dmitry.baryshkov@xxxxxxxxxx>

[ Upstream commit acb94d67f5a23dbb2e0021b6c30609ed05d7d6a5 ]

The USB3 PHY on the QCM2290 platform doesn't have built-in
PCS_MISC_CLAMP_ENABLE register. Instead clamping is handled separately
via the register in the TCSR space. Declare corresponding register.
