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...
