We should probably update the binding documentation for this as well: mfd/wm831x.txt Also I am not sure this needs to be implemented now, but what is the plan regarding pdata systems? Generally the driver supports both and it would be nice to know there is a way forward for that even if we don't implement it yet. Thanks, Charles
