This patch series dedicated to enable those devices. The MFD framework is also updated to cope with interesting implementation of the cell descriptions under ACPI MFD (patch 1). The patches 5 and 6 are pretty independent and could be applied ahead, though they don't make much sense without previous ones. Wolfram, since Lee acknowledged patches 1-3, can you pull them to your tree? Tested on the actual Intel Galileo Gen2 by Ismo (gpio expanders) and me (at24).
