I am not sure what is the benefit of defining these in header. Unlike
other DT consts (e.g. clock IDs) drivers do not us them at all. Using
them in DT does not reduce chance of mistakes in numbers - instead of in
DTS you can make a mistake here in header file. In the same time, they
grow the interrupt property in DTS making it more difficult to read.

I also did not see anyone else using this approach, so it's not only me
(Marc also find it confusing).

If vendor kernel did similar, it's not an argument. Samsung LSI /.
vendor kernel has terrible code quality so usually it is not a good example.


Best regards,
Krzysztof
