Well that's pretty opaque :D

I suppose no datasheet (why do vendors keep doing this to us...)

In other kernel code I have referred to this as a "jam table", e.g.
drivers/net/dsa/rtl8366rb.c.

I didn't make this up, the name comes from Bunnie Huang's
book on hacking the Xbox, and he says it is common hardware
engineer lingo.
https://www.iacr.org/workshops/ches/ches2002/presentations/Huang.pdf

What about naming it nv3052c_jam_table[] or nv3052c_jam[]?

Yours,
