Adding required clock breaks the ABI and there is no explanation nor note about it in commit msg Best regards, Krzysztof

Qualcomm IPQ5332 has a combo PHY for PCIe and USB. Either one of the interface (PCIe/USB) can use this combo PHY and the PHY drivers are different for PCIe and USB. Hence separate the PCIe and USB pipe clock source from DT, and individual driver node can be used as a clock source separately in the gcc. Change the dt-bindings accordingly.
