So for reference there's still quite a bit needed for an accelerated
display than just that panthor driver, there needs to be support for
HDMI controlle which isn't yet upstream but has now at least been
posted[1], and looking at the thread there's some work to do there so
we might still be a little way off for those wanting accelerated
display output. The driver posted is also purely display so no support
for things like HDMI audio and CEC.
