Hi,

so to not break the binding and other boards the right Patch should be like this

@@ -1691,17 +1691,17 @@ static int dwc3_probe(struct platform_device *pdev)

-               dwc->bus_clk = devm_clk_get_optional(dev, "bus_early");

                        return dev_err_probe(dev, PTR_ERR(dwc->bus_clk),
                                             "could not get bus clock\n");

                        return dev_err_probe(dev, PTR_ERR(dwc->ref_clk),
                                             "could not get ref clock\n");

                                             "could not get suspend clock\n");

but this needs fixing dts using the new clock names

this is a link to the series moving from bulk_clk to named clocks:
