This all sounds nice but is very certainly a future piece of work not related to this patch submission. > The newly added Cubieboard2 from your patch appears to be missing the > important AXP209_POWER option. So the patch is not good enough to be > pushed anywhere in its current form. It works for me regardless and always has. The AXP209 config is trivial to add now that Hans has added the relevant code.
