Either use/extend the old binding or remove it if it is not being used. Rob
This set adds USB SS PHY support to Qualcomm's QCS404 SoC The PHY is implemented using Synopsys SS PHY 1.0.0 IP The code is losely based on Sriharsha Allenki's <sallenki@codeaurora.org> original implementation. v2: enable OTG mode detection move vdd voltage levels to driver use bulk_ control interfaces ss-phy-bindings [1] [1] ss-phy-binding discussion: - qcom,dwc3-ss-usb-phy exist for a generic usb2/usb3 phy driver that was never merged. Rather than trying to re-use these bindings (or delete them) I propose that we go ahead with the new separate bindings for HS and SS: if not now - investigation in progress- in the future it might be possible to have again a common phy driver for which these old bindings would be the binding agreement.
