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"

+Freescale Synchronous Audio Interface (SAI).
+
+The SAI is based on I2S module that used communicating with audio codecs,
+which provides a synchronous audio interface that supports fullduplex
+serial interfaces with frame synchronization such as I2S, AC97, TDM, and
+codec/DSP interfaces.
+
+
+Required properties:
+- compatible: Compatible list, contains "fsl,vf610-sai".
+- reg: Offset and length of the register set for the device.
+- clocks: Must contain an entry for each entry in clock-names.
+- clock-names : Must include the "sai" entry.
+- dmas : Generic dma devicetree binding as described in
+  Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names : Two dmas have to be defined, "tx" and "rx".
+- pinctrl-names: Must contain a "default" entry.
+- pinctrl-NNN: One property must exist for each entry in pinctrl-names.
+  See ../pinctrl/pinctrl-bindings.txt for details of the property values.
+- big-endian-regs: If this property is absent, the little endian mode will
+  be in use as default, or the big endian mode will be in use for all the
+  device registers.
+- big-endian-data: If this property is absent, the little endian mode will
+  be in use as default, or the big endian mode will be in use for all the
+  fifo data.
+
+Example:
+sai2: sai@40031000 {
+              compatible = "fsl,vf610-sai";
+              reg = <0x40031000 0x1000>;
+              pinctrl-names = "default";
+              pinctrl-0 = <&pinctrl_sai2_1>;
+              clocks = <&clks VF610_CLK_SAI2>;
+              clock-names = "sai";
+              dma-names = "tx", "rx";
+              dmas = <&edma0 0 VF610_EDMA_MUXID0_SAI2_TX>,
+                   <&edma0 0 VF610_EDMA_MUXID0_SAI2_RX>;
+              big-endian-regs;
+              big-endian-data;
