The values are taken from Amlogic's 3.10 kernel sources. Their sources have a "meson8m2_n200_2G.dtd" which defines a different voltage table: - 0.86V for 96MHz - (values in between omitted) - 1.14V for 1.992GHz The reason for this is simply the hardware design because the voltage regulator on this board is has a minimum output of 0.86V and a maximum output of 1.14V. The recommended settings are added with this patch instead of using the values that are only valid for one board.
