The above is really vauge so it's hard to comment in any detail.  I'm
not sure it's worth trying to be too non-invasive, anything controlling
hardware is going to have to understand what's going on at the physical
level anyway and the host side is going to have to interoperate with the
Slimbus framework.  The core is also going to need to know about the
channel groups to allocate and destroy them as required.  It seems like
being more explicit might be easier.

Also note that the work on submitting your Silmbus driver core to
mainline appears totally stalled, there was just an initial posting but
no followup.
