I am bit confused and need more details than the above line 😄, because

1. We don't have any binding for FF-A and compatible "arm,ffa" is not yet
   defined
2. Even if we have binding, we will not have vm_id and UUID which are
   discoverable from the firmware
3. DT maintainers rejected the bindings when it was initially proposed
   as it is discoverable. If we need it for a valid reason, we need more
   info, this patch doesn't provide full picture to change their stance.

I would like to add minimal binding not for vmid or UUID but for interrupts
only. It is still WIP but I haven't made up my mind on how that should look.
