ALSA: Use a define for the number of jack switch types

2012-02-27T16:34:44+00:00

This is intended to facilitate the merge of the two jack detection
mechanisms.

ALSA: jack - Add "Line In" input jack constants

2011-10-05T15:22:04+00:00

Similar to Line Out, these constants form the base for future
patches enabling input jack reporting for Line in jacks.

ALSA: Add more jack button slots

2010-09-07T06:04:38+00:00

Some devices have more flexible microphone detection and can detect
a wider range of buttons.

ALSA: Add support for key reporting via the jack interface

2010-03-17T18:10:46+00:00

Some devices provide support for detection of a small number of
buttons on their jacks. One common implementation provides a single
button, implemented by shorting the microphone to ground and detected
along with microphone presence detection by detecting varying current
draws on the microphone bias signal.

Provide support for up to three buttons via the jack interface. These
default to reporting BTN_n but an API is provided to allow these to
be remapped to other keys by the machine driver where it knows what
the keys are. More keys can be added with ease if required.

This is only intended to support simple accessory button designs. If
the interface is limiting then either creating a child device for the
accessory or accessing the input device in the jack directly is
recommended.

ALSA: add private_data to struct snd_jack

2009-04-14T14:15:09+00:00

Added private_data and private_free fields to struct snd_jack so that
the caller can assign the data.  It'll be helpful for avoiding the
double-free of the jack instance.

ALSA: Add support for video out to the jack reporting API

2009-01-07T10:55:18+00:00

Add support for reporting new jack types SND_JACK_VIDEOOUT and
SND_JACK_AVOUT (a combination of LINEOUT and VIDEOOUT) to the jack
reporting API.

Also add the corresponding SW_VIDEOOUT_INSERT switch to the input system
header.

ALSA: Reduce boilerplate for new jack types

2009-01-03T17:02:21+00:00

Use a lookup table rather than explicit code to map input subsystem jack
types into ASoC ones, implemented as suggested by Takashi Iwai.
