Why move it?

For organization, to keep all of the USB clocks together. I can leave it alone if that is preferred.

Don't we have clk_set_parent()for that?

Yes. clk_set_parent() is already called in a loop for all clocks elsewhere, so not needed here.

Thank you for the careful review. I will address the other problems you pointed out.
