Yes this is just the phy, other than that things work the same.

I believe this is different from the am335x phy, and more similar to
what we have in old drivers/usb/musb/davinci.c. Chances are dm814x
is same as am335x phy.

But yeah, we really should do a proper phy driver for am335x too
along the same lines. Might even be be able to combine those drivers
with just different compatible values to set the quirks and the
enable/disable functions.
