I don't think that's necessary at the moment, but if we start seeing an
influx of patches to arch/arm64/net, then that could make sense in the
future.

Looks like it works on my Juno board too, so:

  Acked-by: Will Deacon <will.deacon@....com>

for the series.

It's a bit late for 3.17 now, so I guess we'll queue this for 3.18 (which
also means the dependency on -next isn't an issue). Perhaps you could repost
around -rc3?

Cheers,

Will
