Subject: [PATCH v2] mfd: arizona: Move useful defines into a dt-binding include
Move parts of linux/mfd/arizona/pdata.h and gpio.h into a new file in
the dt-binding directory for use by device tree bindings. This also
makes gpio.h redundant so remove it in the process.

Acked-by: Mark Brown <broonie@...nel.org>

Changes since v1:
- Removed some defines that will never be used in DT from the
dt-binding include
- Added some convience defines for the most common pin configs
(input/output/default)
- Updated the binding documentation to use the new defines to
give some context to their usage
Thanks,
Charles
