[alsa-devel] [PATCH v1 0/3] add jack detection to MSM8916 analog

[Damien Riegel]

This series adds support for the MBHC (Multi-Button Headset Control) of
the PM8916's analog codec. This IP is capable to identify up to five
buttons on a headset, but for now only the jack detection is supported.
A complete implementation exists in the Android kernel, but it's quite
complex and I'd rather go step by step.

First patch fixes a define that is squatting a bit used by the MBHC.
Second patch is the actual implementation of the jack detection, and
third patch plugs the jack detection in the sound card driver.
