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!
