Similar to short circuit detection, when the ADC/DAC is saturated and
overflows poor audio quality can result and should be reported to the
user. This device support Automatic Dynamic Range Compression (DRC)
to reduce this but it is not enabled currently in this driver.

These devices support detecting and reporting short circuits across
the output stages. Add support for reporting these issue. Do this
by registering an interrupt if available and enabling this error
to trigger that interrupt in the device.

With P0 R29, Bit2 set the I2S clocks will be running when the DAC/ADC is
powered down, but still the codec need to be powered up by needing at least
one complete DAPM path for the stream.
If the AIF is not needed (analog loopback for example) the I2S clocks will
not run as they are not needed.

We also move the comments describing the registers to after the register
definition to remove non-uniform vertical white-space, this makes
cross-referencing with the datasheet much easier.

The DAC3101 is mostly identical to DAC3100 with the exception that it has
stereo speaker AMP instead of mono used in DAC3100.

tlv320dac31xx is a subset of tlv320aic31xx:
- it does not have MIC inputs and ADC, thus capture is not supported,
- it has analog inputs AIN1/AIN2 that can be mixed into output.
Although tlv320dac31xx does work with tlv320aic31xx driver, this setup
does register non-existent widgets and non-existent capture stream.
Thus userspace lists non-existent objects in user interfaces, an can
access these, causing operations with device registers that are
declared as "reserved" in tlv320dac31xx datasheet.
This patch fixes this situation by separating controls/widgets/routes
into common, aic31xx-specific, and dac31xx-specific parts. Only parts
that match actual hardware (as declared in "compatible" device tree
property) are registered.
Changes from v1:
- update device tree binding documentation,
- rebased on top of "ASoC: codec duplicated callback function goes to
component on tlv320aic31xx" commit.

The datasheet uses decimal numbers for the register addresses, convert the
register values from hexadecimal to decimal and introduce macro for the
register definitions. This way it is easier to look up registers in the
documentation.

S24_LE is the same on the bus as S24_3LE, which means the codec can support

This commit adds a bare bones driver support for TLV320AIC31XX family
audio codecs. The driver adds basic stereo playback trough headphone
and speaker outputs and mono capture trough microphone inputs.
The driver is currently missing support at least for mini DSP features
and jack detection. I have tested the driver only on TLV320AIC3111,
but based on the data sheets TLV320AIC3100, TLV320AIC3110, and
TLV320AIC3120 should work Ok too.
The base for the implementation was taken from:
git@gitorious.org:ti-codecs/ti-codecs.git ajitk/topics/k3.10.1-aic31xx
-branch at commit 77504eba0294764e9e63b4a0c696b44db187cd13.
