Thanks for you comments. Actually in our custom hardware, the codec is not accessible/visible from kernel directly, rather additional MCU controls and configures it. However MCU needs the I2S clocks and data from kernel. So I am using I2S platform driver from Linux just to configure I2S clocks, and registering a dummy codec driver to DAI link in DT, so that codec can be instantiated and clocks can be enabled from user-space ALSA utils while accessing this dummy codec. Please suggest if there is any better way to achieve this kind of configuration.
