Merge tag 'sound-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "The biggest change in this update is the unification of HD-audio codec parsers. Now the HD-audio codec is parsed in a generic parser code which is invoked by each HD-audio codec driver. Some background information is found in David Henningsson's blog entry: http://voices.canonical.com/david.henningsson/2013/01/18/upcoming-changes-to-the-intel-hda-drivers/ Other than that, some random updates/fixes like USB-audio and a bunch of small AoC updates as usual. Highlights: - Unification of HD-audio parser code (aka generic parser) - Support of new Intel HD-audio controller, new IDT codecs - Fixes for HD-audio HDMI audio hotplug - Haswell HDMI audio fixup - Support of Creative CA0132 DSP code - A few fixes of HDSP driver - USB-audio fix for Roland A-PRO, M-Audio FT C600 - Support PM for aloop driver (and fixes Oops) - Compress API updates for gapless playback support For ASoC part: - Support for a wider range of hardware in the compressed stream code - The ability to mute capture streams as well as playback streams while inactive - DT support for AK4642, FSI, Samsung I2S and WM8962 - AC'97 support for Tegra - New driver for max98090, replacing the stub which was there - A new driver from Dialog Note that due to dependencies, DTification of DMA support for Samsung platforms (used only by the and I2S driver and SPI) is merged here as well." Fix up trivial conflict in drivers/spi/spi-s3c64xx.c due to removed code being changed. * tag 'sound-3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (453 commits) ALSA: usb: Fix Processing Unit Descriptor parsers ALSA: hda - hdmi: Notify userspace when ELD control changes ALSA: hda - hdmi: Protect ELD buffer ALSA: hda - hdmi: Refactor hdmi_eld into parsed_hdmi_eld ALSA: hda - hdmi: Do not expose eld data when eld is invalid ALSA: hda - hdmi: ELD shouldn't be valid after unplug ALSA: hda - Fix the silent speaker output on Fujitsu S7020 laptop ALSA: hda - add quirks for mute LED on two HP machines ALSA: usb/quirks, fix out-of-bounds access ASoC: codecs: Add da7213 codec ALSA: au88x0 - Define channel map for au88x0 ALSA: compress: add support for gapless playback ALSA: hda - Remove speaker clicks on CX20549 ALSA: hda - Disable runtime PM for Intel 5 Series/3400 ALSA: hda - Increase badness for missing multi-io ASoC: arizona: Automatically manage input mutes ALSA: hda - Fix broken workaround for HDMI/SPDIF conflicts ALSA: hda/ca0132 - Add missing \n to debug prints ALSA: hda/ca0132 - Fix type of INVALID_CHIP_ADDRESS ALSA: hda - update documentation for no-primary-hp fixup ...
