I would be kinda neutral here. I'd consider it helpful, it improves
readability (regardless of whether they are generated or hand crafted). That's
convenient for things like interrupt sensitivity, I can't remember whether 4
is level or edge type. On the other hand, the clock indices are just as much
magic numbers as the memory addresses. If I suspect an error in that area, I'd
start by lokking in /sys/kernel/debug/clk but wouldn't start in the DT.

I write them by hand. Is there any other way?
