OK it seems like a reasonable process.

It's not like I can think about anything better.

I was more opting for doing things this way:

- Create bindings and <dt-bindings/foo/bar.h> merge it into the
  foo subsystem.

- Merge driver into drivers/foo/bar.c that use <dt-bindings/foo/bar.h>

- Submit DTS patch to ARM SoC (or whetever) using only numerical
  values.

- After the merge window, follow up with a patch replacing the
  numerical constants with #defines from <dt-bindings/foo/bar.h>

An alternative would obviously be to wait for the next merge window
after merging the driver patch but I guess people are too impatient
to do that (including me).

We discussed cross-tree dependencies a bit on ksummit-discuss
but this solution was not mentioned back then.
