Hi Rob,

be specified.

Don't show status in examples.
OK.
This should show the complete node.
I asked this question below in my previous email.
May be you missed it, I hope that you have time soon to answer this so that I
can send a new version.
To be clear, I should take ethernet node from the mt7621.dtsi [0] or
mt7623.dtsi [1] and insert the example below?, right?
Greats,
René
