All of them. I.e. the devicetree is supposed to be compatible with all of those, while the bootloader determines the actual board revision and sets the choosen compatible - at least that was the way with the previous series of devices based around the rk3288 (veyron) and I think it will be the same way still. I.e. as you can see below, Kevin starts being compatible at -rev6, as (engineering) revisions before that probably had some differences on the board. > > > + > > +- Google Kevin: > > + Required root node properties: > > + - compatible = "google,kevin-rev15", "google,kevin-rev14", > > + "google,kevin-rev13", "google,kevin-rev12", > > + "google,kevin-rev11", "google,kevin-rev10", > > + "google,kevin-rev9", "google,kevin-rev8", > > + "google,kevin-rev7", "google,kevin-rev6", > > + "google,kevin", "google,gru", "rockchip,rk3399"; > > + > > > > - mqmaker MiQi: > > Required root node properties: > > - compatible = "mqmaker,miqi", "rockchip,rk3288"; -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
