... according to:
$ git grep bcm43430a1 Documentation/
Documentation/devicetree/bindings/net/broadcom-bluetooth.yaml:
- brcm,bcm43430a1-bt
Documentation/devicetree/bindings/net/wireless/brcm,bcm4329-fmac.yaml:
- brcm,bcm43430a1-fmac
This compatible should be:
compatible = "brcm,bcm43430a1-fmac", "brcm,bcm4329-fmac";
