Merge tag 'sound-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Changes are seen in a wide range of codes, mainly due to ASoC DAPM requirements; HD-audio shows a high peak in diffstat, it's just a removal of bunch of old static quirks. Some highlights: - HDPM: Updates for AIO/RayDAT support, TCO/sync support - RME96: Add PCM sync support - HD-audio: * A few HDMI/DP audio updates (CA assignment fix, stream switching fix, Intel DP device list support) * Device specific fixes (ASUS/CXT HP mic support, Thinkpad mic improvements, Chromebook fixes, STAC9228 Dell fixes) * Replace the all static quirks for AD codecs with the generic parser * WAKEEN support for handling irqs in the power saving mode - USB-audio: Clean up implicit fb handling and related codes - DAPM is now mandatory for ASoC CODEC drivers; all existing drivers have had some level of DAPM support added. In addition, a lot of cleanups and improvements in DAPM. - Support for ASoC cross-platform compile test - New drivers and support for Analog Devices ADAU1702 and ADAU1401(a), Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson Microelectronics WM8997 - DT bindings for kirkwood and i.MX S/PDIF - Clean up and bug fixes: ssm2602, rt5640 and sgtl5000. - Core helpers for bitbanged AC'97 reset" * tag 'sound-3.12' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (375 commits) ALSA: hda - Re-setup HDMI pin and audio infoframe on stream switches ALSA: hda - hdmi: Fallback to ALSA allocation when selecting CA ASoC: mxs-sgtl5000: Configure the dai_links as unidirectional ASoC: soc-pcm: Allow to specify unidirectional dai_link ASoC: fsl_spdif: Staticse non-exported symbols ASoC: ssm2602: Fix cache sync ASoC: Remove unused sysfs_registered field from snd_soc_codec struct ASoC: Remove unused debugfs_dapm field from snd_soc_{platform,codec} struct ASoC: Remove unused control_type field from snd_soc_codec struct ASoC: fsl: Add one blank space after ':=' in Makefile ASoC: fsl: Add wrapping for dev_dbg() in fsl_spdif.c ASoC: rt5640: change widget sequence for depop ASoC: dapm: Fix auto-disable for inverted controls ASoC: fsl: Drop SND_SOC_FSL_UTILS from SND_SOC_IMX_SPDIF ASoC: Samsung: Do not queue cyclic buffers multiple times ASoC: ep93xx-i2s: Remove unnecessary dev_set_drvdata() ASoC: designware_i2s: Remove unnecessary dev_set_drvdata() ASoC: fsl_spdif: remove redundant dev_err call in fsl_spdif_probe() ASoC: fsl: Add S/PDIF machine driver ASoc: kirkwood: Use the Kirkwood audio driver in Dove boards ...
