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.
