I did consider the same approach as Jaroslav (especially as there is still limited number of SOF clients in the wild still), but dropped the idea based on userspace feedback. So in the end, backward compatibility is kept in the patchset just for this reason. The common-hdmi patch adds ability to use SOF with both codec drivers and I even added a module parameter to allow distros to compile both drivers in, and select the driver to use, at runtime from user-space. Slowly as user-space migrates to the new driver (more features), we can at some point drop the old and get rid of "'HDMI/DP, pcm=' notation. Of course, proving there is no one left is not easy, so we likely need to maintain both for a looong time.
