Thanks for your patch, which is now commit de4b9f7e371a5384

This is the only compatible value defined which contains both "k3"
and "j72*". I assume the "k3-" part should be dropped?

This also applies to the driver added in commit 9707a6254a8a6b97
("media: chips-media: wave5: Add the v4l2 layer") in media/master.

Correct - we have not been using architecture prefix such as k3- in
compatibles for any other peripheral and that lines up with DT spec[1]

$ git grep ti, Documentation/|grep compatible|grep yaml|cut -d ':' -f2|grep k3-
is empty.

I have for asked this to be cleared up[2] before I can pick the dts changes
corresponding to the binding.. I will wait for the bindings to hit linus
master prior to looking at the dts changes.
