Merge tag 'sound-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound update from Takashi Iwai: "This is a fairly quiet release in all sound area. Only a little bit of changes in the core side while most of changes are seen in the drivers. HD-audio: - A few new codec additions for Nvidia, Realtek and VIA - Intel Haswell audio support - Support for "phantom" jacks for consistent jack reporting - Major clean-ups in HDMI/DP driver codes - A workaround for inverted digital-mic pins with Realtek codecs - Removal of beep_mode=2 option ASoC: - Added the ability to add and remove DAPM paths dynamically, mostly for reparenting on clock changes - New machine drivers for Marvell Brownstone, ST-Ericsson Ux500 reference platform and ttc-dkp - New CPU drivers for Blackfin BF6xx SPORTs in I2S mode, Marvell MMP, Synopsis Designware I2S controllers, and SPEAr DMA and S/PDIF - New CODEC drivers for Dialog DA732x, ST STA529, ST-Ericsson AB8500, TI Isabelle and Wolfson Microelectronics WM5102 and WM5110 - DAPM fixes for the recent locking changes - Fix for _PRE and _POST widgets (which have been broken for a few releases now) - A couple of minor driver updates Misc - Conversion to new dev_pm_ops in platform and PCI drivers - LTC support and some fixes in PCXHR driver - A few fixes and PM support for ISA OPti9xx and WSS cards - Some TLV code cleanup - Move driver-specific headers from include/sound to local dirs" * tag 'sound-3.6' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (212 commits) ASoC: dapm: Fix _PRE and _POST events for DAPM performance improvements ALSA: hda - add dock support for Thinkpad X230 Tablet ALSA: hda - Turn on PIN_OUT from hdmi playback prepare.
