Well, this got applied quickly, so I guess I can't NAK, but this requires discussion.

It returns an error because it finds no tbi node. Because without the tbi node, there is no way for the driver to determine which address to set.

Your solution is to ignore the error, and hope. That's a broken approach. The real solution for a p1010 should be to have a tbi node in the dts.

And looking at the p1010si.dtsi, I see that it's automatically there for you.

How were you breaking?
