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"
