Pull sound updates from Takashi Iwai:
 "A relative calm release at this time with a flat diffstat.  The only
  significant change in the ALSA core side is the support for more than
  32 card instances, configurable via kconfig.  Other than that, in both
  ASoC and other parts, mostly some improvements and fixes on the driver
  side.

   - hda: Haswell HDMI audio fixes, runtime PM improvements
   - hda: Intel BayTrail support, ALC5505 DSP support
   - es1968: MediaForte M56VAP support
   - usb-audio: Improved support for Yamaha/Roland devices
   - usb-audio: M2Tech hiFace, Audio Advantage Micro II support
   - hdspm: wordclock fixes
   - ASoC: Pending fixes for WM8962

+Wolfson Arizona class audio SoCs
+
+These devices are audio SoCs with extensive digital capabilites and a range
+of analogue I/O.
+
+Required properties:
+
+  - compatible : one of the following chip-specific strings:
+	"wlf,wm5102"
+	"wlf,wm5110"
+  - reg : I2C slave address when connected using I2C, chip select number when
+    using SPI.
+
+  - interrupts : The interrupt line the /IRQ signal for the device is
+    connected to.
+  - interrupt-controller : Arizona class devices contain interrupt controllers
+    and may provide interrupt services to other devices.
+  - interrupt-parent : The parent interrupt controller.
+  - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
+    The first cell is the IRQ number.
+    The second cell is the flags, encoded as the trigger masks from
+    Documentation/devicetree/bindings/interrupts.txt
+
+  - gpio-controller : Indicates this device is a GPIO controller.
+  - #gpio-cells : Must be 2. The first cell is the pin number and the
+    second cell is used to specify optional parameters (currently unused).
+
+  - AVDD1-supply, DBVDD1-supply, DBVDD2-supply, DBVDD3-supply, CPVDD-supply,
+    SPKVDDL-supply, SPKVDDR-supply : power supplies for the device, as covered
+    in Documentation/devicetree/bindings/regulator/regulator.txt
+
+Optional properties:
+
+  - wlf,reset : GPIO specifier for the GPIO controlling /RESET
+  - wlf,ldoena : GPIO specifier for the GPIO controlling LDOENA
+
+  - wlf,gpio-defaults : A list of GPIO configuration register values. If
+    absent, no configuration of these registers is performed. If any
+    entry has a value that is out of range for a 16 bit register then
+    the chip default will be used.  If present exactly five values must
+    be specified.
+
+Example:
+
