Since this is the first usage of this compatible ID, we still have room to
change it to be better. Tony's suggestion was to use "ti,control-phy-am437-usb2"
Please see
http://article.gmane.org/gmane.linux.drivers.devicetree/64833
Okay.

Why disable something that is within the SoC and does not affect board configurations?
Question applies for all the nodes in this patch except the ones that come out on the
SoC pins. e.g. PHY.
Okay

clock-names should be platform independent. Better option would be to
modify the usb2 driver to use names like "wkupclk" and "refclk"
The phy driver still does devm_get_clk using above clock names and not
"wkupclk" and "refclk".

shouldn't this be phys = <&usb2_phy1>; ?
At the time of writing this patch phys property is still not in.
Also generic-phy conversion for dwc3 was recently posted by kishon.

what about
maximum-speed = "high-speed";
and
dr_mode = "otg"; ?
Done from board file. Actually maximum-speed I can set here.
dr_mode is a board property.
