Add device tree support for the dummy codec driver.
Why would this be useful? If the device is a dummy device for internal use obviously it doesn't actually exist which tends to suggest that it shouldn't be represented in the DT either as the DT should describe the hardware.
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.
Thanks, Vishal
