At the hardware level, registers are grouped into IP blocks, to simply 
both design integration and address decoding.  Not knowing which Realtek 
device you're referring to, most likely it's the same situation as with 
the IMX8M TRM, where the DT data doesn't match the underlying reality of 
the hardware.  In those cases the best approach is usually to just fix the 
DT data.
