Is the timer armv8-compatible? I think it is, at least the virtual
timer seems to work as expected.

When looking up the timer information in the guest btw,
where the guest is running AArch64, does it make sense to look
for an armv8-timer compatible string?
Or is the "/timer" path standard enough that I should look for
the node using that fixed path instead?

Thanks,

Claudio
