> After quick look, I do not see backwards compatibility in the driver and > above commit msg tells me nothing about ABI break. For the next version I will state in this commit message the upcoming modifications to DTS and compatibility, why it will be done, and that support for existing DTS is not dropped. Previous `imx-spdif` driver used the dummy codec instead of using declared spdif codecs. It was discussed in previous version of this contribution that using the dummy codec isn't good practice. So one to one backward compatibility isn't really possible. Best regards, Elinor Montmasson
