Merge tag 'sound-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into next
Pull sound updates from Takashi Iwai: "At this time, majority of changes come from ASoC world while we got a few new drivers in other places for FireWire and USB. There have been lots of ASoC core cleanups / refactoring, but very little visible to external users. ASoC: - Support for specifying aux CODECs in DT - Removal of the deprecated mux and enum macros - More moves towards full componentisation - Removal of some unused I/O code - Lots of cleanups, fixes and enhancements to the davinci, Freescale, Haswell and Realtek drivers - Several drivers exposed directly in Kconfig for use with simple-card - GPIO descriptor support for jacks - More updates and fixes to the Freescale SSI, Intel and rsnd drivers - New drivers for Cirrus CS42L56, Realtek RT5639, RT5642 and RT5651 and ST STA350, Analog Devices ADAU1361, ADAU1381, ADAU1761 and ADAU1781, and Realtek RT5677 HD-audio: - Clean up Dell headset quirks - Noise fixes for Dell and Sony laptops - Thinkpad T440 dock fix - Realtek codec updates (ALC293,ALC233,ALC3235) - Tegra HD-audio HDMI support FireWire-audio: - FireWire audio stack enhancement (AMDTP, MIDI), support for incoming isochronous stream and duplex streams with timestamp synchronization - BeBoB-based devices support - Fireworks-based device support USB-audio: - Behringer BCD2000 USB device support Misc: - Clean up of a few old drivers, atmel, fm801, etc" * tag 'sound-3.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (480 commits) ASoC: Fix wrong argument for card remove callbacks ASoC: free jack GPIOs before the sound card is freed ALSA: firewire-lib: Remove a comment about restriction of asynchronous operation ASoC: cache: Fix error code when not using ASoC level cache ALSA: hda/realtek - Fix COEF widget NID for ALC260 replacer fixup ALSA: hda/realtek - Correction of fixup codes for PB V7900 laptop ALSA: firewire-lib: Use IEC 61883-6 compliant labels for Raw Audio data ASoC: add RT5677 CODEC driver ASoC: intel: The Baytrail/MAX98090 driver depends on I2C ASoC: rt5640: Add the function "get_clk_info" to RL6231 shared support ASoC: rt5640: Add the function of the PLL clock calculation to RL6231 shared support ASoC: rt5640: Add RL6231 class device shared support for RT5640, RT5645 and RT5651 ASoC: cache: Fix possible ZERO_SIZE_PTR pointer dereferencing error. ASoC: Add helper functions to cast from DAPM context to CODEC/platform ALSA: bebob: sizeof() vs ARRAY_SIZE() typo ASoC: wm9713: correct mono out PGA sources ALSA: synth: emux: soundfont.c: Cleaning up memory leak ASoC: fsl: Remove dependencies of boards for SND_SOC_EUKREA_TLV320 ASoC: fsl-ssi: Use regmap ASoC: fsl-ssi: reorder and document fsl_ssi_private ...
