The board compatible still looks wrong. According to model it is not the
TI who made it. You need to use proper vendor prefix. Vendor prefix and
board compatible should be documented in the bindings. For the board
compatible this is Documentation/devicetree/bindings/arm/omap/omap.txt I
guess.

This did not improve since last time... the node name does not match
Devicetree spec (generic node name like "ethernet", only lowercase
characters). The compatible is not documented. In fact, it is not a
proper compatible.
Checkpatch should warn you about this.

Please spend some time to make this code look like normal DTS.
Indentation is easy to fix, you do not reviewers to point it out.
