Merge tag 'asoc-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next
ASoC: Additional updates for v3.7 A couple more updates for 3.7, enhancements to the ux500 and wm2000 drivers, a new driver for DA9055 and the support for regulator bypass mode. With the exception of the DA9055 this has all had a chance to soak in -next (the driver was added on Friday so should be in -next today).

This will be one of the same strings reported by
the "state" attribute.

+What: /sys/class/regulator/.../bypass
+Date: September 2012
+KernelVersion: 3.7
+Contact: Mark Brown <broonie@opensource.wolfsonmicro.com>
+Description:
+ Some regulator directories will contain a field called
+ bypass. This indicates if the device is in bypass mode.
+
+ This will be one of the following strings:
+
+ 'enabled'
+ 'disabled'
+ 'unknown'
+
+ 'enabled' means the regulator is in bypass mode.
+
+ 'disabled' means that the regulator is regulating.
+
+ 'unknown' means software cannot determine the state, or
+ the reported state is invalid.

+Cirrus Logic CS4271 DT bindings
+
+This driver supports both the I2C and the SPI bus.
+
+Required properties:
+
+ - compatible: "cirrus,cs4271"
+
+For required properties on SPI, please consult
+Documentation/devicetree/bindings/spi/spi-bus.txt

+Required properties on I2C:
+
+ - reg: the i2c address
+
+
+Optional properties:
+
+ - reset-gpio: a GPIO spec to define which pin is connected to the chip's
+ !RESET pin
+
+Examples:
+
+ codec_i2c: cs4271@10 {

+ reg = <0x10>;
+ reset-gpio = <&gpio 23 0>;
