I'm thinking back to plain Kirkwood. There were 3 Kirkwood SoCs. We had kirkwood.dtsi which described everything common to all three SoCs. And then kirkwood-6192.dtsi, kirkwood-6281.dtsi, kirkwood-6282.dtsi which extended that base with whatever additional things each SoC had. I'm wondering if something similar is needed here? armada-98DX25xx.dtsi which describes everything common to Alleycat5. armada-98DX35xx.dtsi which describes everything common to Alleycat5X, maybe making use of armada-98DX25xx.dtsi?. armada-98DX2538.dtsi which extends armada-98DX25xx.dtsi And then a board file which includes armada-98DX2538.dtsi and add the board specific bits? I've no idea how these different devices differ, so i don't know what the correct hierarchy should be.
