On the other hand, we did this dance last year for some other SoCs. And having to repeat the same list of never-changing aliases for every board was a sore spot for a lot of people it seemed. Most boards follow the reference schematics quite closely afterall. Like very shortly after the last discussion I got patches moving the aliases to their then agreed upon position. (numeric busses in the soc dtsi, everything else in board dts). And back in november we ended with [0] - Krzysztof saying that "it is just generic guideline, so up to Heiko what to do with it" ;-) . I also made sure to send the changes upwards way before christmas to give soc maintainers time to complain if needed and especially did point out that change in my pull request text [1] ;-) .
