Unfortunately it doesn't seem to be the problem here, I added "reg" and
the problem persists, and I've looked at other device trees that contain
"brcm,bcm43438-bt", none of them use "reg", and "reg" is not mentioned in
neither "Documentation/devicetree/bindings/serial/nxp,sc16is7xx.txt" nor
"Documentation/devicetree/bindings/net/broadcom-bluetooth.yaml".


Best regards!
