    ASoC: tlv320aic3x: Support for OCMV configuration · 19b0fa11
    Peter Ujfalusi authored
    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.
