Others have commented on other compatible fields, so it's my turn. :-)

Is this the exact same GIC that's used with A15? I don't think it is? It might
make more sense to use a new compatible field and add it to the driver.

Also, other platforms have removed the a9 fallback, so even if you happen to
have an a15-compatible gic, in this case you should at least take out the a9
string.
