Is 0x10000 the correct maximum addressable size of the external bus in both cases? Intuitively, I would guess that the 0xa0000000 range might be much wider. > .dts > > smb { > ethernet@0,0 { > compatible = "smsc,lan9220", "smsc,lan9115"; > reg = <0 0x0 0x10000>; > interrupts = <13>; > interrupt-parent = <&nvic>; > smsc,irq-active-high; > }; > > > and looking again at .dtsi it seems to me that fpgaio should be moved > below the soc/ under separate bus interface which would hosts audio and > spi too or I keep missing things around device-tree? > I don't see the audio and spi nodes, so I'm not sure where exactly you would put them. Ideally those things should be visible from a block diagram in the datasheet.
