This patch series dedicated to enable those devices. Meanwhile it also changes I2C core to cope with ACPI 6.0 specification (patch 1/8). The MFD framework is also updated to cope with interesting implementation of the cell descriptions under ACPI MFD (patch 2/8). The patches 7 and 8 are pretty independent, though they don't make much sense without previous ones applied. Srinivas, it would be nice to see your tag (ideally Tested-by) to be sure we don't break ISH stuff. Since it touches multiple subsystems someone needs to create an immutable branch. I don't actually know whose subsystem better here. Lee, Wolfram? Apparently we would like to get ACKs / comments from the rest. Tested on the actual Intel Galileo Gen2 by Ismo (gpio expanders) and me (at24).
