compatibility "ti,am4372-cpsw" is not needed as driver has only "ti,cpsw"
compatibility

No, please read device tree documentation [1].

DT is a pure hardware description, it does not depend on driver, 
dependency is only vice versa.

There are many other parameters which are missed here.

Reason has been mentioned in the commit message, quoting relevant here 
again,

I really wanted to avoid a later patch that has a line starting with 
minus on DTS.

Since you are working on cpsw support, can you help here with a patch 
for other properties.
