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"
