You can attach the device to any PCI slot, connect the WLAN antenna and
it just works without DT nodes. I'm trying to make sure here that basic
setup still works.

Adding also Johan and ath11k list. For example, I don't know what's the
plan with Lenovo X13s, will it use this framework? I guess in theory we
could have devices which use qcom,ath11k-calibration-variant from DT but
not any of these supply properties?
