Pull sound updates from Takashi Iwai: "There have been major modernization with the standard bus: in ALSA sequencer core and HD-audio. Also, HD-audio receives the regmap support replacing the in-house cache register cache code. These changes shouldn't impact the existing behavior, but rather refactoring. In addition, HD-audio got the code split to a core library part and the "legacy" driver parts. This is a preliminary work for adapting the upcoming ASoC HD-audio driver, and the whole transition is still work in progress, likely finished in 4.1. Along with them, there are many updates in ASoC area as usual, too: lots of cleanups, Intel code shuffling, etc. Here are some highlights: ALSA core: - PCM: the audio timestamp / wallclock enhancement - PCM: fixes in DPCM management - Fixes / cleanups of user-space control element management - Sequencer: modernization using the standard bus HD-audio: - Modernization using the standard bus - Regmap support - Use standard runtime PM for codec power saving - Widget-path based power-saving for IDT, VIA and Realtek codecs - Reorganized sysfs entries for each codec object - More Dell headset support ASoC: - Move of jack registration to the card level - Lots of ASoC cleanups, mainly moving things from the CODEC level to the card level - Support for DAPM routes specified by both the machine driver and DT - Continuing improvements to rcar - pcm512x enhacements - Intel platforms updates - rt5670 updates / fixes - New platforms / devices: some non-DSP Qualcomm platforms, Google's Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC Misc: - ice1724: Improved ESI W192M support - emu10k1: Emu 1010 fixes/enhancement" * tag 'sound-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (411 commits) ALSA: hda - set GET bit when adding a vendor verb to the codec regmap ALSA: hda/realtek - Enable the ALC292 dock fixup on the Thinkpad T450 ALSA: hda - Fix another race in runtime PM refcounting ALSA: hda - Expose codec type sysfs ALSA: ctl: fix to handle several elements added by one operation for userspace element ASoC: Intel: fix array_size.cocci warnings ASoC: n810: Automatically disconnect non-connected pins ASoC: n810: Consistently pass the card DAPM context to n810_ext_control() ASoC: davinci-evm: Use card DAPM context to access widgets ASoC: mop500_ab8500: Use card DAPM context to access widgets ASoC: wm1133-ev1: Use card DAPM context to access widgets ASoC: atmel: Improve machine driver compile test coverage ASoC: atmel: Add dependency to SND_SOC_I2C_AND_SPI where necessary ALSA: control: Fix a typo of SNDRV_CTL_ELEM_ACCESS_TLV_* with SNDRV_CTL_TLV_OP_* ALSA: usb-audio: Don't attempt to get Microsoft Lifecam Cinema sample rate ASoC: rnsd: fix build regression without CONFIG_OF ALSA: emu10k1: add toggles for E-mu 1010 optical ports ALSA: ctl: fill identical information to return value when adding userspace elements ALSA: ctl: fix a bug to return no identical information in info operation for userspace controls ALSA: ctl: confirm to return all identical information in 'activate' event ...
