[PATCH v1 0/8] enable I2C devices behind I2C bus on Gen2

[Andy Shevchenko <andriy.shevchenko@linux.intel.com>]

There is a board in the wild, i.e. Intel Galileo Gen2, that has ACPI enumerated
devices behind I2C bus.

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).
