ASoC: Additional updates for v3.7

Browse Source 
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).

@ -349,3 +349,24 @@ Description:
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 {
compatible = "cirrus,cs4271";
reg = <0x10>;
reset-gpio = <&gpio 23 0>;
};
codec_spi: cs4271@0 {
compatible = "cirrus,cs4271";
reg = <0x0>;
reset-gpio = <&gpio 23 0>;
