Looks like you have cleaned up some unneeded includes. Thats fine, just
mention it in the commit description too, so its clear that it is intended.
Also, when adding new include files, please do it in alphabetical order.

NULL device name here is wrong. There is a PHY device that gets added
3/5. The name of that device should appear here. Since that phy device
is the consumer of this clock. You can change the order of patches so
the device appears before the associated clocks.

here too, please have the phy device name as the consumer of this clock.
It is okay to have NULL device name for the usb_refclkin since that is a
root clock not associated with any device.
