could you think about changing patches 3 and 4 with the diff below?

For one the comment style is not really following the coding style.
I guess either remove the comments completely or switch to a /* ... */
form.

More importantly, I think the compatible is a property of the SoC and does
not need to be replicated into every board, so it should live in a small
&emac node in the rk3188.dtsi to adapt the property.
