Ah, I see what you mean. But these registers and interrupt are actually
only visible on the hypervizor side. The guest shouldn't see any of this.

Rihgt, that makes sense.

I suppose we could have a "arm,has-virt-extensions" property in devices
that implement the virtualization extensions (GIC, timers...).

What do you think?

Sounds good. I don't have a strong preference whether that should be a
property like you suggest or a separate "compatible" value, maybe Rob or
Grant can comment on what they prefer.

I don't have a strong opinion either way.  This approach looks fine.
