dt-bindings: sound: tlv320aic3x: Convert to dtschema
Convert bindings for TI's TLV320AIC3x audio codecs to dtschema. The following properties are still found in some old dts files, but will be ignored by the driver: - adc-settle-ms - port Signed-off-by: Jai Luthra <j-luthra@ti.com> Reviewed-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20221221145216.11400-1-j-luthra@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>

title: Texas Instruments TLV320AIC3x Codec
|
||||
|
||||
description: |
|
||||
TLV320AIC3x are a series of low-power stereo audio codecs with stereo
|
||||
headphone amplifier, as well as multiple inputs and outputs programmable in
|
||||
single-ended or fully differential configurations.
|
||||
|
||||
The serial control bus supports SPI or I2C protocols, while the serial audio
|
||||
data bus is programmable for I2S, left/right-justified, DSP, or TDM modes.
|
||||

||||
