[PATCH v4 0/8] Add basic microphone detection bindings

From: Charles Keepax
Date: Fri Jun 19 2015 - 08:52:00 EST

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.

Changes since v1:
- Removed double include of property.h

Changes since v2:
- Removed check for CONFIG_OF to call
- Add some defines for the pdata values of micd-dbtime.
- Factor out the initial gpio level for the micd-pol-gpio.
- Don't check if null before calling gpiod_set_value_cansleep.
- Added a comment to explain why we can't use devm for gpiod.
- Added patch to make some small corrections to the jack
detection into this series to keep them all together for
easy of applying.

Changes since v3:
- Simplify the symantics of the pdata for micd_dbtime
