2015-05-19ALSA: hda/ca0132: support for Alienware 15 Creative Sound Core3D-EXGabriele Martino
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 Reding
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.

Baytrail/Braswell For Baytrail (Valleyview) and Braswell (Cherryview), only the HDMI codec is in the display power well while the HD-A controller isn't.

2015-04-29ALSA: hda - divide controller and codec dependency on i915 gfx power wellMengdong Lin
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.

2015-04-27ALSA: jack: implement kctl creating for jack devicesJie Yang
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.

2015-04-27ALSA: emu10k1: Fix card shortname string buffer overflowTakashi Iwai
Some models provide too long string for the shortname that has 32bytes including the terminator, and it results in a non-terminated string exposed to the user-space. This isn't too critical, though, as the string is stopped at the succeeding longname string. This patch fixes such entries by dropping "SB" prefix (it's enough to fit within 32 bytes, so far). Meanwhile, it also changes strcpy() with strlcpy() to make sure that this kind of problem won't happen in future, too. Cc: <stable@vger.kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>

Dell XPS13 produces a click noise at boot up, and Gabriele spotted out that it's triggered by the initial pin control of the mic (NID 0x19). This has to be set to Hi-Z Vref while the driver initializes to Vref 80% as a normal mic. This patch fixes the generic parser code not to override the target vref if it has been already set by the driver, and adds a proper initialization of the target vref for this pin in the Realtek driver side.

2015-04-24ALSA: core: Remove child proc file elements recursivelyTakashi Iwai
This patch changes the way to manage the resource release of proc files: namely, let snd_info_free_entry() freeing the whole children. This makes it us possible to drop the snd_device_*() management. Then snd_card_proc_new() becomes merely a wrapper to snd_info_create_card_entry(). Together with this change, now you need to call snd_info_free_entry() for a proc entry created via snd_card_proc_new(), while it was freed via snd_device_free() beforehand.

We have two machines with alc256 codec in the pin quirk table, so moving the common pins to ALC256_STANDARD_PINS.

2015-04-21ALSA: hda - fix "num_steps = 0" error on ALC256David Henningsson
The ALC256 does not have a mixer nid at 0x0b, and there's no loopback path (the output pins are directly connected to the DACs). This commit fixes an "num_steps = 0 for NID=0xb (ctl = Beep Playback Volume)" error (and as a result, problems with amixer/alsamixer). If there's pcbeep functionality, it certainly isn't controlled by setting an amp on 0x0b, so disable beep functionality (at least for now).

2015-04-21ALSA: hda - add AZX_DCAPS_I915_POWERWELL to BaytrailMengdong Lin
This patch addes AZX_DCAPS_I915_POWERWELL to BYT (Baytrail). Like Braswell and Skylake, the HDMI codec on Bytrail is also in the shared power well with GPU. This power well must be turned on before we reset link to probe the codec, to avoid communication failure with the codec. The side effect is that this power is always ON in S0 because the BYT HDMI codec does not support EPSS or D3ClkStop and so the controller doesn't enter D3 at runtime, and the HDMI codec and analog codec share a single physical HD-A link and so we cannot reset the HD-A link freely when we re-enable the power to use the HDMI codec. Next step is to test if an AGP reset or double AGP reset on BYT HDMI codec is okay to bring the HDMI codec back to a functional state after restoring the power. If okay, we can bind the power on/off with the HDMI codec PM without interrupting the analog audio. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
