I am sorry to jump in here at such a late stage with a (potentially)
trivial question. "ls2k" is the SoC family rather than a specific model
as far as I understand.
The answer is probably yes, but do all SoCs in the family have an
identical version of the IP?

No, but the spi supported by this loongson spi driver are all the same
identical version, and other type or verion spi will be supported as
needed in the future.
