I assume the "k3-" part should be dropped? 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.
