In general, I can try to add and use new compat strings "ti,netcp-k2hk" "ti,netcp-k2l" "ti,netcp-k2e" "ti,netcp-k2g" for determining CPTS capabilities.
CPTS version is not the choice due to very poor documentation which do not allow identify relations between CPTS ver and supported features :(
Murali, what do you think?
