    ASoC: rt5651: Allow specifying the OVCD scale-factor through a device-property · e6eb0207
    Hans de Goede authored
    OVer-Current-Detection (OVCD) for the micbias current is used to detect if
    an inserted jack is a headset or headphones (mic shorted to ground).
    
    The threshold for at which current the OVCD triggers on the rt5651 is not
    only controlled by setting the absolute current limit, but also by setting
    a scale factor which applies to the limit. Testing has shown that we need
    to set both (depending on the board).
    
    This commit adds support for the sofar unused OVCD scale-factor register
    and adds support for specifying non-default values for it through the
    "realtek,over-current-scale-factor" device-property.
