Did you run at least dt_bindings_check? The compatible should be just "samsung,s3fwrn82".

I fixed it as below and ran dt_bindings_check. compatible: oneOf: - enum: - samsung,s3fwrn5-i2c - samsung,s3fwrn82 > The compatible should be just "samsung,s3fwrn82".

Sorry. I don't understand this comment. Could you explain it? Does it mean i need to refer to the net/broadcom-bluetooth.txt? > > Best regards, > Krzysztof

The node name should be "bluetooth", not "s3fwrn82_uart", because of Devicetree naming convention - node names should represent generic class of a device. Best regards, Krzysztof

Oops, of course, nfc, I don't know why the Bluetooth stuck in my mind. Best regards, Krzysztof
