Some controllers like DWC3 and CDNS3 manage phy in their core drivers. This property can be set to avoid phy initialization in HCD core. v4: Added the device tree binding patch in the series. v3: Coming back to this series based on discussion at below thread https://patchwork.kernel.org/project/linux-arm-msm/patch/1648103831-12347-4-git-send-email-quic_c_sanm@quicinc.com/ Dropped the dt bindings PATCH 1/3 in v2 https://patchwork.kernel.org/project/linux-arm-msm/cover/1636353710-25582-1-git-send-email-quic_c_sanm@quicinc.com/ v2: Updated the commit descriptions. Changed subject prefix from dwc to dwc3. Increased props array size.
