OK. I will move resets to optional property. Please let ask a question. The number of clocks should be the same across SoCs. (Even if there is no s/w control for clocks, we should input something such as clk-fixed-rate.) On the other hand, the number of resets can be different across SoCs. If there is no s/w control for resets, we can make it optional. (optional = 1 or 0 reset) Is this what you mean? If we had something like reset-nop (or reset-dummy) in case no s/w control, we would be able to input something. I am not sure if this is the right thing, though. > Otherise, for the DT binding: > > Reviewed-by: Rob Herring <robh@xxxxxxxxxx> > -- Best Regards Masahiro Yamada -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
