This is no different from the way we handle *any* bus that uses the
GICv3 ITS as an MSI controller. Each bus provides its glue code that
latches onto the ITS node, and calls into the generic code.

Now, when it comes to moving this out of staging, here is my concern:
There is mention of a userspace tool (restool) used to control the
HW. Where is this tool? Where is the user ABI documented?

Thanks,
