Yes, I know, but in this case an exception makes sense.
I prefer to use the exact same register mnemonics as in the hardware

the driver with hardware manual in hand (and they should be doing that
way) will immediately see the connection.

I am not sure. What does cpu_relax() do exactly, and when is it safe
