Currently MCLK rate depends on following DT properties, * 'mclk-fs' : This is a scaling factor depending on which MCLK rate is calculated at runtime [rate = scale * sample_rate]. Different codecs might expect different scale factors and hence DT property is useful here. * 'nvidia,mclk-rate' : This is used to provided fixed rate for MCLK. This overrides scale property, when specified. Since the requirement is either to have fixed or dynamic rate for MCLK, this can be managed with single property like below. * Use 'assigned-clocks' and 'assigned-clock-parents' to specify parent clock for MCLK. * Use preferred rate during initialization with 'assigned-clock-rates' DT binding. This can be the required fixed rate as well. * If dynamic scaling is required, then use 'mclk-fs' property. Otherwise system uses fixed rate. Since rt565x audio codecs expect scaling factor of 256, all platforms which use such codecs must be populated with "mclk-fs" property. This is taken care in other patches in the series.
