So I guess the question then: do we need to keep this board at all? Or it is time for it to go the way of the dodo? And then we could drop some more drivers as well. My goal for the series was to move along legacy gpio API conversions, as well as move away from the GPIO lookup tables (ideally I want them gone now that we have software nodes supporting describing GPIOs).
