Yeah.. FYI, the way to get there is to have a generic interonnect
target agent driver for the module, then have the device ip
instance(s) just be children of the interconnect target. But
it will be a while until I can start posting those patches.

Until that's available, we can have minimal device specific
interconnect target module drivers just like we have
drivers/usb/musb/musb_am335x.c. That's the parent for two
musb instances and one cppi41 dma instance. See also the
related "usb@47400000" node in am33xx.dtsi and it's children.

Regards,

Tony
