Suggested edit:

ASoC: Intel: sof_nau8825: add variant with nau8318 amplifier.

That should be added in the commit message please.

Ok, makes sense now. Please do include the explanations on 8315/8318
variants, I couldn't figure out what chips were used.

I would also not use the same topology name as a different platform with
another amplifier. I appreciate you trying to reuse when possible, but
it's just better to create a new topology file. That way if you want any
update down the road you can do so, it's more maintainable and risk-free.
