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.
