Maybe the dts needs to be split up instead? Looks like the gpio drivers
are in a uniphier directory and there is some precedence to keep the
"taken over" company name when vendors are merged into other vendors.
Maybe that's how things have happened here? It would be nice to be
consistent, but I leave the decision up to you to figure out if that
really matters to you. I'll be fine either way.
