Texas Instruments - tlv320aic3x Codec module
The tlv320aic3x serial control bus communicates through I2C protocols
Required properties:
ASoC: tlv320aic3x: Add compatible strings for specific devices The driver supports a range of devices but currently doesn't allow those device names to be used for enumeration on DT. Add the currently listed I2C IDs as compatible strings. Signed-off-by: Mark Brown <broonie@linaro.org>

ASoC: tlv320aic3x: Rename property for reset GPIO The property used to specify a GPIO intended for reset is "reset-gpios", but this binding uses "gpio-reset". It is not compatible with newer methods used to fetch GPIO pins and to prevent the spread of this error to other bindings let's rename to be more standard. We also standardize the pin as active-low, different device trees have marked the GPIO different ways, luckily the driver currently uses the low-level GPIO set function which does not respect the active-low flag, but future changes may change this. This is an active-low reset, mark it as such. Lastly, add an example of use for this property. [Rewrote title & first paragraph for clarity & accuracy -- broonie] Signed-off-by: Andrew F.

- Not supported on tlv320aic3104
ASoC: tlv320aic3x: Convert mic bias to a supply widget Convert MicBias widgets to supply widget. On tlv320aic3x, Mic bias power on/off shares the same register bits with output mic bias voltage. So, when power on mic bias, we need reclaim it to voltage value. Provide a new platform data so that the micbias voltage can be sent according to board requirement. Now since tlv320aic3x codec driver is DT aware, update dt files and functions to handle this new "micbias-vg" platform data. Because of sharing of bits, when enabling the micbias, voltage also needs to be updated. So use SND_SOC_DAPM_POST_PMU & SND_SOC_DAPM_PRE_PMD macro to create an event to handle this. Since micbias is converted to supply widget, updated machine drivers as well. This change is runtime tested on da850-evm with audio loopback (arecord|aplay) for confirmation.

- ai3x-micbias-vg - MicBias Voltage required.
1 - MICBIAS output is powered to 2.0V,
2 - MICBIAS output is powered to 2.5V,
3 - MICBIAS output is connected to AVDD,
If this node is not mentioned or if the value is incorrect, then MicBias
is powered down.
ASoC: tlv320aic3x: Support for OCMV configuration In aic3x class of devices Output Common-Mode Voltage can be configured for better analog performance. The OCMV value depends on the Analog and digital domain power supply voltage configuration. The default OCMV of 1.35V gives best performance when AVDD is around 2.7V and DVDD is 1.525V, but for higher AVDD/DVDD higher OCMV setting is recommended. The patch gives an automatic way of guessing the best OCMV which can be overwritten by a DT parameter if needed.
