As you know, I am using two of your complex drivers, namely
ethernet and interrupt controller (which would have taken me
several weeks to write). I will be submitting them upstream
shortly, is that OK with you?

I'm not using this particular driver of yours because I had
already written the code, and porting it to DT was a good
learning process. This is probably my only opportunity to
actually write any kind of code for this port.

Regards.
