Merge tag 'sound-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "It was holiday season, so no wonder that there are little changes in framework level, although diffstat shows quite many changes spreaded over sound/* directories. Most of changes are cleanups, code refactoring and fixes. Some highlights: - Removal of OSS sleep_on usages by Arnd - Simplified memalloc helper codes, drop obsoleted features; now it's built into PCM driver instead of an individual module - Warn if PCM buffer preallocation fails, which will show page allocation issues more clearly - Compress offload API updates for sample rates by Vinod - PCM glitch workaround on ctxfi emu20k1 by Sarah - Drop cs46xx DSP blobs, using firmware loader now - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420, and Focusrite Saffire 6 HD-audio specifics: - Standardize Kconfigs of HD-audio codec drivers; now "make localmodconfig" recognizes configs properly (finally!) - Parallel PM implementation by Mengdong - BayleyBay/ValleyView2 board fixups - Broadwell audio support - Runtime PM improvement (PantherPoint, etc) - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity, Dell AiO click noise fixes, Dell headset mic fixes, etc - Automatic bind with HDMI codec parser without generic parser - More AD codec fixes (since 3.12 regression) including the automatic stereo mix support - Common Thinkpad ACPI helper for Realtek and Conexant codecs ASoC specifics: - Update to the generic DMA code to support deferred probe and managed resources - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090 and Analog Devices AXI I2S and S/PDIF controller IPs - Device tree support for the simple card, max98090 and cs42l52 - Conversion of the Samsung drivers to native dmaengine, making them multiplatform compatible and hopefully helping keep them more modern and up to date. - More regmap conversions, including a very welcome one for twl6040 from Peter Ujfalusi - A big overhaul of the DaVinci drivers also from Peter Ujfalusi - Lots of DMA updates from Lars-Peter - Improvements to the constraints handling code from Lars-Peter - A very helpful conversion of the TWL4030 driver to regmap from Peter - A new driver for the Freescale ESAI controller from Nicolin Chen - Conversion of some of the drivers to use params_width() - Extensions to DPCM for use with compressed audio from Liam" * tag 'sound-3.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (396 commits) ASoC: dapm: Fix double prefix addition ASoC: compress: Add suport for DPCM into compressed audio ASoC: DPCM: make some DPCM API calls non static for compressed usage ASoC: core: Fix possible NULL pointer dereference of pcm->config ALSA: hda - add headset mic detect quirks for some Dell machines ASoC: tlv320aic32x4: Fix regmap range_min ASoC: core: Return -ENOTSUPP from set_sysclk() if no operation provided ASoC: dapm: Change prototype of soc_widget_read ASoC: samsung: Remove SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag ASoC: axi-{spdif,i2s}: Remove SND_DMAENGINE_PCM_FLAG_NO_RESIDUE flag ASoC: generic-dmaengine-pcm: Check DMA residue granularity ASoC: generic-dmaengine-pcm: Check NO_RESIDUE flag at runtime dma: pl330: Set residue_granularity dma: Indicate residue granularity in dma_slave_caps ASoC: simple-card: fix one bug to writing to the platform data ASoC: pcm: Use snd_pcm_rate_mask_intersect() helper ALSA: Add helper function for intersecting two rate masks ASoC: s6000: Don't mix SNDRV_PCM_RATE_CONTINUOUS with specific rates ASoC: fsl: Don't mix SNDRV_PCM_RATE_CONTINUOUS with specific rates ASoC: pcm: Properly initialize hw->rate_max ...
