Merge tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "There have been lots of changes in ALSA core, HD-audio and ASoC, also most of PCI drivers touched by conversions of printks. All these resulted in a high volume and wide ranged patch sets in this release. Many changes are fairly trivial, but also lots of nice cleanups and refactors. There are a few new drivers, most notably, the Intel Haswell and Baytrail ASoC driver. Core changes: - A bit modernization; embed the device struct into snd_card struct, so that it may be referred from the beginning. A new snd_card_new() function is introduced for that, and all drivers have been converted. - Simplification in the device management code in ALSA core; now managed by a simple priority list instead - Converted many kernel messages to use the standard dev_err() & co; this would be the pretty visible difference, especially for HD-audio. HD-audio: - Conexant codecs use the auto-parser as default now; the old static code still remains in case of regressions. Some old quirks have been rewritten with the fixups for auto-parser. - C-Media codecs also use the auto-parser as default now, too. - A device struct is assigned to each HD-audio codec, and the formerly hwdep attributes are accessible over the codec sysfs, too. hwdep attributes still remain for compatibility. - Split the PCI-specific stuff for HD-audio controller into a separate module, ane make a helper module for the generic controller driver. This is a preliminary change for supporting Tegra HDMI controller in near future, which slipped from 3.15 merge. - Device-specific fixes: mute LED support for Lenovo Ideapad, mic LED fix for HP laptops, more ASUS subwoofer quirks, yet more Dell laptop headset quirks - Make the HD-audio codec response a bit more robust - A few improvements on Realtek ALC282 / 283 about the pop noises - A couple of Intel HDMI fixes ASoC: - Lots of cleanups for enumerations; refactored lots of error prone original codes to use more modern APIs - Elimination of the ASoC level wrappers for I2C and SPI moving us closer to converting to regmap completely and avoiding some randconfig hassle - Provide both manually and transparently locked DAPM APIs rather than a mix of the two fixing some concurrency issues - Start converting CODEC drivers to use separate bus interface drivers rather than having them all in one file helping avoid dependency issues - DPCM support for Intel Haswell and Bay Trail platforms, lots of fixes - Lots of work on improvements for simple-card, DaVinci and the Renesas rcar drivers. - New drivers for Analog Devices ADAU1977, TI PCM512x and parts of the CSR SiRF SoC, TLV320AIC31XXX, Armada 370 DB, Cirrus cs42xx8 - Fixes for the simple-card DAI format DT mess - DT support for a couple more devices. - Use of the tdm_slot mapping in a few drivers Others: - Support of reset_resume callback for improved S4 in USB-audio driver; the device with boot quirks have been little tested, which we need to watch out in this development cycle - Add PM support for ICE1712 driver (finally!); it's still pretty partial support, only for M-Audio devices" * tag 'sound-3.15-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (610 commits) ALSA: ice1712: Add suspend support for M-Audio ICE1712-based cards ALSA: ice1712: add suspend support for ICE1712 chip ALSA: hda - Enable beep for ASUS 1015E ALSA: asihpi: fix some indenting in snd_card_asihpi_pcm_new() ALSA: hda - add headset mic detect quirks for three Dell laptops ASoC: tegra: move AC97 clock handling to the machine driver ASoC: simple-card: Handle many DAI links ASoC: simple-card: Add DT documentation for multi-DAI links ASoC: simple-card: dynamically allocate the DAI link and properties ASoC: imx-ssi: Add .xlate_tdm_slot_mask() support.
