ASoC: Updates for v3.11

Browse source 
Not a big release subsystem wise, the main changes have been some nice
 improvements on the driver side:
 
 - Lots of cleanups and fixes for Blackfin, SGTL5000 and UX500.
 - Generalisation of the Bluetooth and HDMI stub drivers.
 - New CODEC drivers for SSM2518 and RT5640.
 - New machine driver for Tegra CPUs with RT5640.

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:
codec: wm5102@1a {
compatible = "wlf,wm5102";
reg = <0x1a>;
interrupts = <347>;
#interrupt-cells = <2>;
interrupt-parent = <&gic>;

and ADDR1, as wired in hardware.
Optional properties:
- reset-gpio: A GPIO spec to define which pin is connected to the
chip's !RESET pin. If specified, the driver will
assert a hardware reset at probe time.
