The SM8550 SoC uses Synopsis eUSB2 PHY. Add a dt-binding schema for the new driver. Signed-off-by: Abel Vesa <abel.vesa@linaro.org> --- There will be a binding check warning from Rob's bot because of the tcsr clock bindings missing (dt-bindings/clock/qcom,sm8550-tcsr.h), but that is expected as the header is already merged through Bjorn's clocks tree.
