This patch adds a binding that describes the Rockchip usb PHYs
found on Rockchip SoCs usb interface.
Technically the bindings patch is supposed to come before the driver.
So this should be patch #1 and the driver patch #2.

You don't have any sub nodes and are using the phy-cells.  Seems like
you should get rid of this?  ...or I guess switch to using sub nodes
and set "phy-cells" to 0?
Oh.  You actually have them in the ".dtsi" patch, but not here in the
example.  Hrm.  I don't know enough about phys in general to say
whether they're needed (I will learn if someone else on this thread
doesn't just know), but if they are required then they ought to be in
the example...
