2009-04-14ALSA: add private_data to struct snd_jackTakashi Iwai
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. Signed-off-by: Takashi Iwai <tiwai@suse.de>

2009-02-18ALSA: jack - Use card->shortname for input nameTakashi Iwai
Currently the jack layer refers to card->longname as a part of its input device name string. However, longname is often really long and way too ugly as an identifier, such as, "HDA Intel at 0xf8400000 irq 21". This patch changes the code to use card->shortname instead. The shortname string contains usually the h/w vendor and product names but without messy I/O port or IRQ numbers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2009-01-07ALSA: Add support for video out to the jack reporting APIJani Nikula
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.

2009-01-03ALSA: Reduce boilerplate for new jack typesMark Brown
Use a lookup table rather than explicit code to map input subsystem jack types into ASoC ones, implemented as suggested by Takashi Iwai. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

2008-12-10ALSA: Add support for mechanical jack insertionMark Brown
Some systems support both mechanical and electrical jack detection, allowing them to report that a jack is physically present but does not have any functioning connections. Add a new jack type for these, allowing user space to report faulty connections. Thanks to Guillem Jover for the suggestion.

2008-10-27ALSA: jack: lineout support to jack abstraction layerMatthew Ranostay
This patch introduces support for reporting SW_LINEOUT_INSERT detection events via the jack abstraction layer. Also adds a SND_JACK_LINEOUT define to the input system header.

2008-10-27ALSA: hda: dynamic jack idMatthew Ranostay
This patch duplicates the jack->id pointer with kstrdup() to prevent scoping issues from calling autoprobing functions from the HDA section.

2008-10-16ALSA: Handle NULL jacks in snd_jack_report()Mark Brown
Facilitate drivers that wish to carry on if they can't create a jack input device by handling attempts to report the state of a NULL jack, removing the need to check for initialisation before use.

2008-07-29ALSA: Add jack reporting APIMark Brown
Currently very few systems provide information about jack status to user space, even though many have hardware facilities to do detection. Those systems that do use an input device with the existing SW_HEADPHONE_INSERT switch type to do so, often independently of ALSA. This patch introduces a standard method for representing jacks to user space into ALSA. It allows drivers to register jacks for a sound card with the input subsystem, binding the input device to the card to help user space associate the input devices with their sound cards. The created input devices are named in the form "card longname jack" where jack is provided by the driver when allocating a jack. By default the parent for the input device is the sound card but this can be overridden by the card driver. The existing user space API with SW_HEADPHONE_INSERT is preserved.
