[PATCH 02/10] dt-bindings: phy: qcom,ipq806x-usb-phy-hs: document the MSM8974 HS PHY
From: Dmitry Baryshkov
Date: Mon Aug 10 2026 - 07:44:12 EST
The MSM8974 DWC3 wrapper contains the same generation of Synopsys 28nm
HS PHY as IPQ806x, controlled through the QSCRATCH registers, but the
binding only covers IPQ806x, leaving the MSM8974 controller to run on
bootloader-configured PHY state.
Add the qcom,msm8974-usb-phy-hs compatible.
