In my opinion, that warning is overstated. There's a fair amount more work involved in using sopc2dts on an "unsupported" kernel than on the officially supported one, but it's still a lot less effort than writing the dts by hand. > I would need a bit more information between which IP blocks are > supported in mainline Linux and device tree examples would help. Aside from the ones that ship with stock kernel sources these days? - Lowell _______________________________________________ Rfi mailing list Rfi@lists.rocketboards.org http://lists.rocketboards.org/cgi-bin/mailman/listinfo/rfi
