If that's not obvious from the define name, then fix the define name.
Looks like in most cases it is.

I can appreciate that and perhaps if this was something imported at
some frequency then it would be worthwhile to maintain formatting. But
this is an ABI and defined by the hardware (as opposed to BPMP
firmware) so it generally shouldn't ever change. And bindings should
be complete, so if you plan periodic additions to it, that's a
separate problem.

Generally, we don't accept doxygen comments in the kernel tree.
There's only a handful of cases that seem to have sneaked in.
