Hi Roger,

Sorry I missed something in the previous revision :-(

You should add that you update the usb_otg_hs node accordingly as well.

In omap-usb.txt, ti,has-mailbox is still marked as mandatory whereas the 
ctrl-module is optional.

You should update the usb-otg-hs bindings as well.

BTW, why is that property not prefixed with "ti,"? Is ctrl-module really 
meaningful for other arch?
