Are INTF_n blocks implemented in silicon or not? What happens if one reads one of INTF_2 or INTF_4 registers? If they are actually RAZ or cause data aborts, you can not reuse SA8775P catalog entry. Please add corresponding data structures to dpu_8_4_sa8775p.h. > > > > >> - qcom,sa8775p-dpu > >> - qcom,sm8650-dpu > >> - qcom,x1e80100-dpu > >> > >> -- > >> 2.34.1 > >> > > > -- With best wishes Dmitry
