Merge tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull updates of sound stuff from Takashi Iwai: "Here is the first big update chunk of sound stuff for 3.4-rc1. In the common sound infrastructure, there are a few changes for dynamic PCM support (used in ASoC) and a few clean-ups. Majority of changes are found, as usual, in HD-audio and ASoC. Some highlights of HD-audio changes: - All the long-standing static quirk codes for Realtek codec were finally removed by fixing and extending the Realtek auto-parser. - The mute-LED control is standardized over all HD-audio codec drivers using the extended vmaster hook. - The vmaster slave mixer elements are initialized to 0dB as default so that the user won't be annoyed by the silent output after updates, e.g. due to the additions of new elements. - Other many fix-ups for the misc HD-audio devices. In the ASoC side, this is a very active release, including a quite a few framework enhancements. Some highlights: - Support for widgets not associated with a CODEC, an important part of the dynamic PCM framework. - A library factoring out the common code shared by dmaengine based DMA drivers contributed by Lars-Peter Clausen. This will save a lot of code and make it much easier to deploy enhancements to dmaengine. - Support for binary controls, used for providing runtime configuration of algorithm coefficients. - A new DAPM widget type for regulator supplies allowing drivers for devices that can power down unused supplies while active to do without any per-driver code. - DAPM widgets for DAIs, initially giving a speed boost for playback startup and shutdown and also the basis for CODEC<->CODEC DAI link support. - Support for specifying the number of significant bits on audio interfaces, useful for allowing applications to know how much effort to put into generating data for a larger sample format. - Conversion of the FSI driver used on some SH processors to DMAEngine. - Conversion of EP93xx drivers to DMAEngine. - New CODEC drivers for Maxim MAX9768 and Wolfson Microelectronics WM2200. - Move audmux driver from arc/arm to sound/soc - McBSP move from arch/ to sound/ and updates Also, a few small updates and fixes for other drivers like au88x0, ymfpci, USB 6fire, USB usx2yaudio are included." * tag 'sound-3.4' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (446 commits) ASoC: wm8994: Provide VMID mode control and fix default sequence ASoC: wm8994: Add missing break in resume ASoC: wm_hubs: Don't actively manage LINEOUT_VMID_BUF ASoC: pxa-ssp: atomically set stream active masks ASoC: fsl: p1022ds: tell the WM8776 codec driver that it's the master ASoC: Samsung: Added to support mono recording ALSA: hda - Fix build with CONFIG_PM=n ALSA: au88x0 - Avoid possible Oops at unbinding ALSA: usb-audio - Fix build error by consitification of rate list ASoC: core: Fix obscure leak of runtime array ALSA: pcm - Avoid GFP_ATOMIC in snd_pcm_link() ALSA: pcm: Constify the list in snd_pcm_hw_constraint_list ASoC: wm8996: Add 44.1kHz support ALSA: hda - Fix build of patch_sigmatel.c without CONFIG_SND_HDA_POWER_SAVE ASoC: mx27vis-aic32x4: Convert it to platform driver ALSA: hda - fix printing of high HDMI sample rates ALSA: ymfpci - Fix legacy registers on S3/S4 resume ALSA: control - Fixe a trailing white space error ALSA: hda - Add expose_enum_ctl flag to snd_hda_add_vmaster_hook() ALSA: hda - Add "Mute-LED Mode" enum control ...
