...and what?

Why is this board-specific?  Isn't the controller part of the SoC, not  
part of the board?  If it really is board-specific, could you be more  
detailed about why (ideally with an erratum number), and check the  
toplevel board compatible (or get the information from platform code)  
rather than modify the device tree?
