While I don't object to Peter Rosin being listed here if he wants it,
I suspect that you added him because he was the author of
"i2c-arb.txt". I guess that file was really only added to try to keep
things common between this GPIO arbitrator and the one that he cares
about: "nxp,pca9541.txt". Probably he doesn't want to be added here.

Speaking of "nxp,pca9541.txt", it seems like you need to convert that
before removing "i2c-arb.txt". It still refers to that file even after
your patch, doesn't it?

In any case, other than that, this looks fine. Thanks for doing the conversion!
