2013-01-12ALSA: hda - Fix multi-io channel mode managementTakashi Iwai
The multi-io channels can vary not only from 1 to 6 but also may vary from 6 to 8 or such. At the same time, there are more speaker pins available than the primary output pins. So, we need three variables to check: the minimum channel counts for primary outputs, the current channel counts for primary outputs, and the minimum channel counts for all outputs.

2013-01-12ALSA: hda - Add snd_hda_gen_free() and snd_hda_gen_check_power_status()Takashi Iwai
Just to remove duplicated codes. Also fixed EXPORT_SYMBOL() in hda_generic.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add pcm_playback_hook to hda_gen_specTakashi Iwai
The new hook which is called at each PCM playback ops. It can be used to control the codec-specific power-saving feature in each codec driver. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Drop bind-volume workaroundTakashi Iwai
The bind-volume workaround was introduced for simplifying the mixer abstraction in the case where one or more pins of multiple outputs lack of individual volume controls. This was essentially the case like Acer Aspire 5935, which has 5.1 speakers and 5.1 (multi-io) jacks although there are 5 DACs, so some of them must share a DAC. However, the recent code rewrite changed the DAC assignment policy to share with the same channel instead of binding to the front, thus binding the volumes for all channels makes little sense now, rather it's confusing. So in this patch, the ugly workaround is finally dropped and simply create the volume control corresponding to the parsed path position. For dual headphones or 2.1 speakers with a shared volume control, it's anyway bound to the same DAC if needed, so this change shouldn't bring any practical difference. And, as a good bonus, we can cut off the whole code handling the bind volume elements. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add Loopback Mixing controlTakashi Iwai
For codecs that have individual routes going through a loopback mixer (like VIA codecs), we need to provide an explicit switch to choose whether the output goes through mixer or directly from DAC. This patch adds the check for such paths and creates "Loopback Mixing" enum control when available. It won't influence on codecs like Realtek or others where the loopback mixer is connected independently from the primary output routes. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Initialize digital-input path properlyTakashi Iwai
Call the path activation for the digital input pin properly, not only setting the pin control. Also add spec->digin_path for keeping the path index. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Manage using output/loopback path indicesTakashi Iwai
Instead of search for the path with the certain route at each time, keep the path index for each output and loopback, and just use it when referred. In this implementation, the path index number begins with one, not zero (although I've been writing in C over decades). It's just to make the check for uninitialized values easier. So far, the input paths aren't handled with indices yet, but still picked up via snd_hda_get_nid_path() at each time. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Check the existing path in snd_hda_add_new_path()Takashi Iwai
If the requested path has been already added, return the existing path instance instead of adding a duplicated instance. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add hooks for HP/line/mic auto switchingTakashi Iwai
... as a preliminary work for migrating patch_sigmatel.c. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Implement independent HP controlTakashi Iwai
Similar like the implementation in patch_analog.c and patch_via.c, the generic parser can provide the independent HP PCM stream now. It's enabled when spec->indep_hp is set by the caller while parsing. Currently no dynamic PCM switching as in patch_via.c is implemented yet. The control returns -EBUSY when the value is changed during PCM operations. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Define HDA_PARSE_* for snd_hda_parse_nid_path() argumentTakashi Iwai
... instead of numbers. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Drop spec->channel_mode field from hda_gen_specTakashi Iwai
It's never used in the generic parser. It was there from the old Realtek code, which has been dropped quite ago, too. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add spec->vmaster_mute_enum flag to generic parserTakashi Iwai
Add a flag to indicate whether the vmaster mute hook enum is exposed or not. Conexant codecs may want not to expose the control depending on the model. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Begin HDA_GEN_* event tag from 1Takashi Iwai
... to distinguish from the invalid event type. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Increase the max depth of widget connectionsTakashi Iwai
Old codecs like AD1986A tend to have long paths as they were just made to be the way like AC97. The current max depth 5 can be too short for such devices. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Export standard jack event handlers for generic parserTakashi Iwai
These handlers are supposed to be called externally from the codec drivers once when they need to handle own jack events. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Move the call of snd_hda_parse_pin_defcfg() from ↵Takashi Iwai
snd_hda_gen_parse_auto_config() In some cases, we want to manipulate the auto_pin_cfg table before passing to snd_hda_gen_parse_auto_config() (e.g. Realtek SSID check code fiddles with the headphone pin). Also passing ignore_pins just for snd_hda_parse_pin_defcfg() isn't good. In this patch, snd_hda_gen_parse_auto_config() is changed to receive the auto_pin_cfg table to be parsed. The passed auto_pin_cfg table must have been initialized (typically by calling snd_hda_gen_parse_auto_config()) beforehand by the caller. Also together with this change, spec->parse_flags is also removed. Since this was referred only at the place calling snd_hda_parse_pin_defcfg(), no longer needed to be kept in spec.

2013-01-12ALSA: hda - Export snd_hda_gen_add_kctl()Takashi Iwai
It may be used in other codec drivers, so let it free. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Add EAPD control to generic parserTakashi Iwai
Enable EAPD in output path initializations automatically unless the new flag spec->own_eapd_ctl is set. Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-01-12ALSA: hda - Merge Realtek parser code to generic parserTakashi Iwai
Finally the whole generic parser code in Realtek driver is moved into hda_generic.c so that it can be used for generic codec driver. The old dumb generic driver is replaced. Yay. The future plan is to adapt this generic parser for other codecs, i.e. the codec driver calls the exported functions in generic driver but adds some codec-specific fixes and setups. As of this commit, the complete driver code is still duplicated in Realtek codec driver. The big code reduction will come from now on. Signed-off-by: Takashi Iwai <tiwai@suse.de>
