Hi Patrick General, the device tree binding and the needed changes to the driver to implement the binding are in the same patchset. I don't see anything implementing qcom,ath12k-calibration-variant here? Does the driver already support this, and you are just fixing up missing documentation? Andrew

The realities of Linux being the de facto upstream for device tree bindings force me to submit changes here so they end up being usable for other operating systems as well. I would assume that eventually someone that runs Linux will adjust the ath12k driver as well, because this kind of binding has been used for both ath10k and ath11k and this is just a copy with a name change for ath12k. Cheers, Patrick

Paraphrasing a certain company.. Linux <3 OpenBSD! Since as you mentioned Linux is the de facto upstream for dt-bindings, many people identify those two.. I think a solution that would keep everyone reasonably happy is dropping a line about your usage in the cover letter Konrad
