I don't understand why SoC specific compatible "intel,socfpga-agilex-hsotg" is able to be added, but the SoC specific compatible "intel,socfpga-stratix10-hsotg" is not allowed. You said "Where is SoC specific compatible?" Now, I add the SoC specific compatible "intel,socfpga-stratix10-hsotg", but why it is still not reasonable. Thanks, Limeng > > > Best regards, > Krzysztof
