2015-05-20ALSA: hda - Move hda_i915.c from sound/pci/hda to sound/hdaMengdong Lin11-280/+313
The file is moved to hda core and renamed to hdac_i915.c, so can be used by both legacy HDA driver and new Skylake audio driver. - Add snd_hdac_ prefix to the public APIs. - The i915 audio component is moved to core bus and dynamically allocated. - A static pointer hdac_acomp is used to help bind/unbind callbacks to get this component, because the sound card's private_data is used by the azx chip pointer, which is a legacy structure. It could be removed if private _data changes to some core structure which can be extended to find the bus. - snd_hdac_get_display_clk() is added to get the display core clock for HSW/BDW. - haswell_set_bclk() is moved to hda_intel.c because it needs to write the controller registers EM4/EM5, and only legacy HD-A needs it for HSW/BDW. - Move definition of HSW/BDW-specific registers EM4/EM5 to hda_register.h and rename them to HSW_EM4/HSW_EM5, because other HD-A controllers have different layout for the extended mode registers.

2015-05-19ALSA: hda - Fix NULL dereference from CA0132 DSP loaderTakashi Iwai1-3/+9
The CA0132 DSP loader leads to NULL deference since the recent transition to HDA core code, as it unconditionally accesses hdac_stream->substream->runtime. For DSP loading, the substream shouldn't be assigned. This patch addresses the NULL dereference above in addition to assure the substream is cleared while DSP loading.

2015-05-19ALSA: hda/ca0132: support for Alienware 15 Creative Sound Core3D-EXGabriele Martino1-26/+92
This patch adds quirks detection to the Creative CA0132 codec, and the quirk for Alienware 15 (2015). Some quirks may need different pin configuration, so the relevant compile-time configuration has been removed. The pin configuration and related initialization verbs are generated at runtime instead, in ca0132_config() and ca0132_prepare_verbs().

2015-05-18ALSA: hda/hdmi - Implement Tegra-specific patchThierry Reding1-1/+166
The HDMI codec on NVIDIA Tegra SoCs has a feature that doesn't exist on the MCP or GPU variants. The highest bit in the vendor-defined scratch registers can be used to trigger an interrupt in the HDMI codec, which is signalled to the HDMI driver. This can be used to pass information, such as the HDA format, to the HDMI driver so that it can reconfigure itself accordingly. While at it, change the name of the codec to Tegra124 since there are no other SoCs in the Tegra12x family. There isn't really a Tegra12x family.

2015-05-18ALSA: info: Register proc entries recursively, tooTakashi Iwai2-15/+40
The commit [c560a6797e3b: ALSA: core: Remove child proc file elements recursively] converted snd_card_proc_new() with the normal snd_info_*() call and removed snd_device chain for such info entries. However, it misses one point: the creation of the proc entry was managed by snd_device chain in the former code, and now it's also gone, which results in no proc files creation at all. Mea culpa. This patch makes snd_info_card_register() creating the all pending child proc entries in a shot. Also, since snd_card_register() might be called multiple times, this function is also changed to be callable multiple times. Along with the changes above, now the linked list of snd_info_entry is added at creation time instead of snd_info_register() for keeping eyes of pending info entries.

snd_info_free_entry() releases the all children nodes as well, but due to the wrong timing of releasing the link, the children nodes may be disconnected but left unreleased. This patch fixes it by moving the link free at the right position. Also it eases list_for_each_entry() without _safe option in snd_info_disconnect() because it no longer frees the children nodes there.

2015-04-29ALSA: hda - divide controller and codec dependency on i915 gfx power wellMengdong Lin2-8/+28
This patch can improve power saving for Intel platforms on which only the display audio codec is in the shared i915 power well: - Add a flag "need_i915_power" to indicate whether the controller needs the i915 power well. - The driver will always request the i915 power when probing the controller and codecs if AZX_DCAPS_I915_POWERWELL is set (either the controller or a codec needs this power). - If the controller needs the i915 power, the power will be held after probe until the controller is runtime suspended or S3. If the controller doesn't need the power, the power will be released the after probe, and a codec that needs the power can request/release the power via bus link_power ops. Background: - For Haswell/Broadwell, which has a separate HD-A controller for display audio, both the controller and the display codec are in the i915 power well. - For Baytrail/Braswell, the display and analog audio share the same HDA controller and link, and only the display codec is in the i915 power well. - For Skylake, the display and analog audio share the same HDA controller but use separate links. Only the display codec is in the i915 power well. And in legacy mode we take the two links as one. So it can follow Baytrail/Braswell.

2015-04-28ALSA: emux: Fix mutex deadlock in OSS emulationTakashi Iwai2-16/+22
The OSS emulation in synth-emux helper has a potential AB/BA deadlock at the simultaneous closing and opening: close -> snd_seq_release() -> sne_seq_free_client() -> snd_seq_delete_all_ports(): takes client->ports_mutex -> port_delete() -> snd_emux_unuse(): takes emux->register_mutex open -> snd_seq_oss_open() -> snd_emux_open_seq_oss(): takes emux->register_mutex -> snd_seq_event_port_attach() -> snd_seq_create_port(): takes client->ports_mutex This patch addresses the deadlock by reducing the rance taking emux->register_mutex in snd_emux_open_seq_oss(). The lock is needed for the refcount handling, so move it locally. The calls in emux_seq.c are already with the mutex, thus they are replaced with the version without mutex lock/unlock.

Add documentation describing Jack kcontrols and how to use them with HD-Audio and ASoC. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

snd_kctl_jack_new() and snd_kctl_jack_report() are internal only now so make them static. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>

2015-04-27ALSA: hda - Update to use the new jack kctls methodJie Yang6-74/+31
Jack snd_kcontrols can now be created during snd_jack_new() or by later calling snd_jack_add_new_kctls(). This patch creates the jacks during the initialisation stage for both phantom and non phantom jacks. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-27ALSA: jack: extend snd_jack_new to support phantom jackJie Yang5-17/+33
Dont create input devices for phantom jacks. Here, we extend snd_jack_new() to support phantom jack creating: pass in a bool param for [non-]phantom flag, and a bool param initial_jack to indicate whether we need to create a kctl at this stage. We can also add a kctl to the jack after its created meaning we can now integrate the HDA and ASoC jacks. Signed-off-by: Jie Yang <yang.jie@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2015-04-27ALSA: Jack: handle jack embedded kcontrol creating within ctljackJie Yang4-6/+37
This patch adds a static method get_available_index() to allocate the index of new jack kcontrols and also adds jack_kctl_name_gen() which is used to ensure compatibility with jack naming by removing " Jack" from some incorrectly passed names.

2015-04-27ALSA: jack: implement kctl creating for jack devicesJie Yang5-7/+103
Currently the ALSA jack core registers only input devices for each jack registered. These jack input devices are not readable by userspace devices that run as non root. This patch series will implement kctls inside the core jack part, including kctls creating, status changing report, for both HD-Audio and ASoC jack. This allows non root userspace to read jack status and act on it. This patch adds a new API called snd_jack_add_new_kctl(), which will create a kcontrol, add it to the card, and also attach it to the jack kctl list. This patch also initialises the jack kctl list after jack is newed, and reports kctl status when jack insertion/removal events occur. snd_jack_new() is updated in the following patches to also support creating phantom jacks and jack kcontrols. We then remove these duplicated features from HDA jack and have jack kctls handled by core throughout HDA and ASoC.
