...and what?
Why is this board-specific? Isn't the controller part of the SoC, not =20
part of the board? If it really is board-specific, could you be more =20
detailed about why (ideally with an erratum number), and check the =20
toplevel board compatible (or get the information from platform code) =20
rather than modify the device tree?
