Hi Rob,

Thank you for your comments.

I'll apply dwc3-of-simple framework for core part and separate phy part
from the driver, and as a result the clocks will be separated into clocks
for core and phy.

The core clocks will be described with "clock-names" property like Qualcomm's
dwc3 driver in Documentation/devicetree/bindings/usb/qcom,dwc3.txt.

I think the remaining clocks will be also defined with clock-names properties
or fixed according to the compatible string in the phy driver.

Same as above.
