From: Peter Ujfalusi peter.ujfalusi@nokia.com

Merge the recently introduced soc_value_enum structure to the soc_enum. The value based enums are still handled separately from the normal enum types, but with the merge some of the newly introduced functions can be removed.

This patch adds a jack reporting interface to ASoC. This wraps the ALSA core jack detection functionality and provides integration with DAPM to automatically update the power state of pins based on the jack state.

Since embedded platforms can have multiple detecton methods used for a single jack (eg, separate microphone and headphone detection) the report function allows specification of which bits are being updated on a given report.

The expected usage is that machine drivers will create jack objects and then configure jack detection methods to update that jack.
