Merge tag 'sound-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "Mostly many small changes spread as seen in diffstat in sound/* directory by this update. A significant change in the subsystem level is the introduction of snd_soc_component, which will help more generic handling of SoC and off-SoC components. Also, snd_BUG_ON() macro is enabled unconditionally now due to its misuses, so people might hit kernel warnings (it's a good thing for us). - compress-offload: support for capture by Charles Keepax - HD-audio: codec delay support by Dylan Reid - HD-audio: improvements/fixes in generic parser: better headphone mic and headset mic support, jack_modes hint consolidation, proper beep attach/detachment, generalized power filter controls by David Henningsson, et al - HD-audio: Improved management of HDMI codec pins/converters - HD-audio: Better pin/DAC assignment for VIA codecs - HD-audio: Haswell HDMI workarounds - HD-audio: ALC268 codec support, a few new quirks for Chromebooks - USB: regression fixes: USB-MIDI autopm fix, the recent ISO latency fix by Clemens Ladisch - USB: support for DSD formats by Daniel Mack - USB: A few UAC2 device endian/cock fixes by Eldad Zack - USB: quirks for Emu 192kHz support, Novation Twitch DJ controller, Yamaha THRxx devices - HDSPM: updates for TCO controls by Adrian Knoth - ASoC: Add a snd_soc_component object type for generic handling of SoC and off-SoC components by Kuninori Morimoto, - dmaengine: a large set of cleanups and conversions by Lars-Peter Clausen - ASoC DAPM: performance optimizations from Ryo Tsutsui - ASoC DAPM: support for mixer control sharing by Stephen Warren - ASoC: multiplatform ARM cleanups from Arnd Bergmann - ASoC: new codec drivers for AK5385 and TAS5086 from Daniel Mack" * tag 'sound-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (315 commits) ALSA: usb-audio: caiaq: fix endianness bug in snd_usb_caiaq_maschine_dispatch ALSA: asihpi: add format support check in snd_card_asihpi_capture_formats ALSA: pcm_format_to_bits strong-typed conversion ALSA: compress: fix the states to check for allowing read ALSA: hda - Move Thinkpad X220 to use auto parser ALSA: USB: adjust for changed 3.8 USB API ALSA: usb - Avoid unnecessary sample rate changes on USB 2.0 clock sources sound: oss/dmabuf: use dma_map_single ALSA: ali5451: use mdelay instead of large udelay constants ALSA: hda - Add the support for ALC286 codec ALSA: usb-audio: USB quirk for Yamaha THR10C ALSA: usb-audio: USB quirk for Yamaha THR5A ALSA: usb-audio: USB quirk for Yamaha THR10 ALSA: usb-audio: Fix autopm error during probing ALSA: snd-usb: try harder to find USB_DT_CS_ENDPOINT ALSA: sound kconfig typo ALSA: emu10k1: Fix dock firmware loading ASoC: ux500: forward declare msp_i2s_platform_data ASoC: davinci-mcasp: Add Support BCLK-to-LRCLK ratio for TDM modes ASoC: davinci-pcm, davinci-mcasp: Clean up active_serializers ...
