The rt5677 codec has gained code that requires SPI to work correctly,
but there is no provision in Kconfig to prevent the driver from
being used when SPI is disabled or a loadable module, resulting
in this build error:

sound/built-in.o: In function `rt5677_spi_write':
:(.text+0xa7ba0): undefined reference to `spi_sync'
sound/built-in.o: In function `rt5677_spi_driver_init':
:(.init.text+0x253c): undefined reference to `spi_register_driver'

ERROR: "spi_sync" [sound/soc/codecs/snd-soc-rt5677-spi.ko] undefined!
ERROR: "spi_register_driver" [sound/soc/codecs/snd-soc-rt5677-spi.ko] undefined!

This makes the SPI portion of the driver depend on the SPI subsystem,
and disables the function that uses SPI for firmware download if SPI
is disabled. The latter may not be the correct solution, but I could
not come up with a better one.

The TS3A227E is an autonomous audio accessory detection and
configuration switch that detects 3-pole or 4-pole audio accessories
and configures internal switches to route the signals accordingly.

This chip also has built-in support for the new button standard
described in the Android "Wired audio headset specification" v1.0.
These buttons will be reported on the jack as buttons 0-3 mapped to
KEY_MEDIA, KEY_VOLUMEUP, KEY_VOLUMEDOWN, and KEY_VOICE_COMMAND.

This will be added as an aux_dev and have the jack passed in from the
machine driver.

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.

When the SigmaDSP module is built-in, but the I2C core is build as a module
we'll get a undefined reference:

	sound/built-in.o: In function `sigma_action_write_i2c':
		:(.text+0x5d8d4): undefined reference to `i2c_master_send'

This can happen if a audio driver that is using the regmap SigmaDSP interface is
built into the kernel, but core I2C support is build as a module. To fix this
split the SigmaDSP module into three modules, one module providing the core
infrastructure and two small modules implementing the regmap and I2C interfaces.
This allows e.g. the core infrastructure and regmap support to be built into the
kernel while I2C support can still be build as a module.
