+
+As per binding documentation [1], the DWC3 core should have the "ref",
+"bus_early" and "suspend" clocks. As explained in the binding, those
+clocks are required for new platforms but not for existing platforms
+before commit fe8abf332b8f ("usb: dwc3: support clocks and resets for
+DWC3 core").
+
+However, as those clocks are really treated as required, this ends with
+having some annoying messages when the "rockchip,rk3399-dwc3" is used:
+
+[    1.724107] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2
+[    1.731893] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2
+[    2.495937] dwc3 fe800000.dwc3: Failed to get clk 'ref': -2
+[    2.647239] dwc3 fe900000.dwc3: Failed to get clk 'ref': -2
+
+In order to remove those annoying messages, update the DWC3 hardware
+module node and add all the required clocks. With this change, both, the
+glue node and the DWC3 core node, have the clocks defined, but that's
+not really a problem and there isn't a side effect on do this. So, we
+can get rid of the annoying get clk error messages.
