As far as I can see, no. Waveshare kits have an extra ASIC in front of
ICN6211 / ICN6202, which completely hides all programming. So far the
interface is really better expressed by the waveshare,dsi2dpi /
dsi2lvds: this way, even if they decide to change the actual
implementation (like they did for DPI -> LVDS), we won't have to worry
about it for as long as their programming interface remains stable.
