* ALSA: jack - Use card->shortname for input nameTakashi Iwai2009-02-181-1/+1
| | | | | | | | | | | | | 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>

| * ALSA: Add support for mechanical jack insertionMark Brown2008-12-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* ALSA: Add jack reporting APIMark Brown2008-07-291-0/+163
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.
