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

[Charles Keepax <ckeepax-yzvPICuk2AATkU/dhu1WVueM+bqZidxxQQ4Iyu8u01E@public.gmane.org>]

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
   arizona_extcon_device_get_pdata.
 - 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

Thanks,
Charles
