This patch can go in as is and we can have another patch when more
accurate capabilities are determined. If/when I have time I can go and
deduce what the capability settings should be on BCM2835. I should be
revisiting this IP for other reasons in the next month or so and will
try to look into it.

Yes, if Arasan allowed such document to be published that would help...
