Hi Kapil,

I tested this on Northstar 1.

Acked-by: Hauke Mehrtens <hauke@...ke-m.de>
Tested-by: Hauke Mehrtens <hauke@...ke-m.de>

I think Florian has to take the patches and you should hurry up because
the merge window probably opens on Monday.

You can send all patches again with the bcm501x patch or just that one,
I assume there are no changes needed for the other patches?
