This is not a property of a board, but is the actual limit documented
by Allwinner for the A20. Some individual SoCs might have wider
tolerances, but that's not a property of a board, it's really a
property of a single SoC, and we cannot make any assumption on the
board.

(and please make sure to run checkpatch before sending your patches)

Thanks!
