can-transceiver is chhild node. dts like this

&can0 {                                                                                             
        status = "okay";                                                                            
                                                                                                    
        can-transceiver {                                                                           
                max-bitrate = <5000000>;                                                            
        };                                                                                          
};

Or, I can simple said

"Add 'can-transceiver' children node for fsl,flexcan."

'can-transceiver' should be common child node for CAN node.
