Multiple devices from the ADAU family share the same PLL structure and

used to calculated the PLL configuration registers based on a specified
input frequency and the desired output frequency of the PLL.
The ADAU1761/ADAU1781 and ADAU1373 drivers are updated to make use of this

This patch adds Realtek ALC286 codec driver.
ALC286 is a dual mode codec, which can run as HD-A or I2S mode.
It is controlled by HD-A verb commands via I2C protocol.
The following is the I/O difference between ALC286 and general I2S codecs.
1. A HD-A verb command contains three parts, NID, VID, and PID.
And an I2S command contains only two parts: address and data.
2. Not only the register address is written, but the read command also
includes the entire write command.
3. rt286 uses different registers for read and write the same bits.
We map verb command to regmap structure. However, we read most registers from
cache to prevent the asymmetry read/write issue in rt286.

devices. They are a family of 4-channel differential input audio ADC devices.
They can be connected to either a SPI or I2C bus. The driver is implemented in
three modules, one main module (adau1977.ko) which implements the device logic
and one module each for SPI (adau1977-spi.ko) and I2C (adau1977-i2c.ko) bus
access.

There are a few known (minor) problems with having the support code for both I2C
and SPI in the same module:
* We need to be extra careful to make sure to not build the driver into the
kernel if one of the subsystems is build as a module (Currently only I2C
can be build as a module).
* The module init path error handling is rather ugly. E.g. what should be
done if either the SPI or the I2C driver fails to register. Most drivers
that implement SPI and I2C in the same module currently fallback to
undefined behavior in that case. Splitting the the driver into two
modules, one for each bus, allows the registration of the other bus drive
to continue without problems if one of them fails.
This patch splits the ADAV80X driver into 3 modules. One core module that
implements the device logic, but is independent of the bus method used. And one
module for SPI and I2C each that registers the drivers and sets up the regmap
struct for the bus.

While we are at it also cleanup the include section of the ssm2602 driver and
remove unneeded includes.

The PCM512x devices are a family of monolithic CMOS integrated circuits
that include a stereo digital-to-analog converter and additional support
circuitry.
This is an initial driver which supports some core functionality for the
device which covers common use cases but does not cover all features.
Currently only slave clocking modes with automatic clock configuration
are supported and most of the DSP configuration for the device is not
enabled.

The wm8997 is a compact, high-performance audio hub CODEC with SLIMbus
interfacing, for smartphones, tablets and other portable audio devices
based on the Arizona platform.
This patch adds the wm8997 CODEC driver.
[Fixed some interface churn from bitrot due to the patch not going via
the MFD tree as expected -- broonie]

Add PCM1792A spi mode codec support. This version implements only
a subset of functionalities. Tested connect to a pandaboard ES
