* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (526 commits) ASoC: twl6040 - Add method to query optimum PDM_DL1 gain ALSA: hda - Fix the lost power-setup of seconary pins after PM resume ALSA: usb-audio: add Yamaha MOX6/MOX8 support ALSA: virtuoso: add S/PDIF input support for all Xonars ALSA: ice1724 - Support for ooAoo SQ210a ALSA: ice1724 - Allow card info based on model only ALSA: ice1724 - Create capture pcm only for ADC-enabled configurations ALSA: hdspm - Provide unique driver id based on card serial ASoC: Dynamically allocate the rtd device for a non-empty release() ASoC: Fix recursive dependency due to select ATMEL_SSC in SND_ATMEL_SOC_SSC ALSA: hda - Fix the detection of "Loopback Mixing" control for VIA codecs ALSA: hda - Return the error from get_wcaps_type() for invalid NIDs ALSA: hda - Use auto-parser for HP laptops with cx20459 codec ALSA: asihpi - Fix potential Oops in snd_asihpi_cmode_info() ALSA: hdsp - Fix potential Oops in snd_hdsp_info_pref_sync_ref() ALSA: hda/cirrus - support for iMac12,2 model ASoC: cx20442: add bias control over a platform provided regulator ALSA: usb-audio - Avoid flood of frame-active debug messages ALSA: snd-usb-us122l: Delete calls to preempt_disable mfd: Put WM8994 into cache only mode when suspending ... Fix up trivial conflicts in: - arch/arm/mach-s3c64xx/mach-crag6410.c: renamed speyside_wm8962 to tobermory, added littlemill right next to it - drivers/base/regmap/{regcache.c,regmap.c}: duplicate diff that had already come in with other changes in the regmap tree

+WM8903 audio CODEC
+
+This device supports I2C only.
+
+Required properties:
+
+ - compatible : "wlf,wm8903"
+
+ - reg : the I2C address of the device.
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+
+ - #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters (currently unused).
+
+Optional properties:
+
+ - interrupts : The interrupt line the codec is connected to.
+
+ - micdet-cfg : Default register value for R6 (Mic Bias). If absent, the
+ default is 0.
+
+ - micdet-delay : The debounce delay for microphone detection in mS. If
+ absent, the default is 100.
+
+ - gpio-cfg : A list of GPIO configuration register values. The list must
+ be 5 entries long. If absent, no configuration of these registers is
+ performed. If any entry has the value 0xffffffff, that GPIO's
+ configuration will not be modified.
+
+Example:
+
+codec: wm8903@1a {
+ compatible = "wlf,wm8903";
+ reg = <0x1a>;
+ interrupts = < 347 >;
+
