Hi Jacobe,

Using the driver implementation as an argument for adding the fallback 
compatible to the bindings does sound wrong. The most importants rule 
about the bindings is that it is independent of kernel and/or driver 
implementation.

Now this actually overlaps my patch series from couple of weeks ago 
which also covered some other existing DTS files for Apple platforms. So 
my proposal here is to drop this patch for now. I will give it another 
shot in v2 of my series after yours is (finally) applied. We can always 
hope ;-) That does also mean the compatible check in the driver should 
not be moved in brcmf_of_probe(). Also the Khadas Edge2 DTS file should 
not use the fallback compatible yet. I can include it in my series later.

Regards,
Arend
