Runtime suspend of phy drivers was failing from DWC3 driver as runtime usage value is 2 because the phy is initialized from DWC3 core and HCD core. 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@xxxxxxxxxxx/ 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@xxxxxxxxxxx/ v2: Updated the commit descriptions. Changed subject prefix from dwc to dwc3. Increased props array size.
