I would imagine the SBU uart requires a jig or some other config..

Could you put that information in the commit message?

It'd be better if you introduced a new label for the bt node and
referred to it by that label here

This comment is a little redundant

Is that fw different to other SDM845 LG firmwares?

Is it? Most of the other firmware paths are relative to /lib/firmware/qcom/sdm845/LG/judyln, while this one is /lib/firmware/qca/judyln
