I see you combined those three arrays in the next patch, thanks!

btw. just an idea, but you don't need to explicitly use 
usb_base_address[CONFIG_USB_MAX_CONTROLLER_COUNT], you can
just use usb_base_address[] in the array definition. Then,
in the code, you can just use "ARRAY_SIZE(usb_base_address) - 1"
instead of CONFIG_USB_MAX_CONTROLLER_COUNT . This rids you of
one annoying macro in that driver ;-) If you want to implement
this, then please do so, but in a separate patch.

I'll pick these two patches now.

Thanks!

Best regards,
Marek Vasut
