[PATCH 0/5] Add basic microphone detection bindings

[Charles Keepax]

This series adds basic microphone detection DT/ACPI bindings
using the device properties API.

The MFD parts and the extcon parts can go seperately through
there respective trees, but I sent them together so everyone
can see what is going on. There is no build dependency
although the MFD patch will fix a couple of Sparse warnings
that you get if using -Wsparse-all.

Thanks,
Charles

[PATCH 1/5] extcon: arizona: Update to use the new device properties API

[Charles Keepax]

The device properties API will load data from both device tree and ACPI,
update the binding to use this API instead of the OF API.

[PATCH 5/5] mfd: arizona: Update several pdata members to unsigned

[Charles Keepax]

Device tree and ACPI primarily deal with unsigned ints, many of the
pdata members in the Arizona driver are signed ints but are only ever
assigned positive values. Changing these pdata fields to unsigned ints
avoids us having to choose between overly verbose code and Sparse
warnings.
