It is good practice to add the new compatible entry. I get your point here. But for the moment it is identical with "fsl,imx7d-sdma" so there is no need to add it now!

I'm not convinced about this. I try to separate patches like this in order for people to really understand step by step how audio is enabled on i.MX board. I will give a second thought though. Maybe 3/5 and 4/5 could be squashed together. > > Also, please make the Subject as: arm64: dts: imx8mq-evk when a patch > is specific to the imx8mq-evk dts. Indeed, will fix in next version.
