As mentioned, you need to Cc the USB mailing list and the EHCI maintainers:

$ ./scripts/get_maintainer.pl drivers/usb/host/ehci-vt8500.c -f

I would list the interrupts and reg properties as required as well,
and you can mention that there must be exactly one interrupt and one
reg resource with a length of 0x200 bytes.
