Web3.3.1 Setting SAI as a master clock provider []. The SAI peripheral can provide a clock to an external component (such as a codec) through the mclk output pin. In this case, it acts as master clock (mclk) provider. The below DT sample gives an example of SAI configuration as mclk provider.. In this example the codec driver supports mclk input based on ASoC …
