This is the patch series I would have written, had I been smart enough. Reviewed-by: Linus Walleij <linus.walleij@xxxxxxxxxx> for the series. I can't test the SIM.ONE board with this until next week but the approach is definately what we want, not just for legacy boards, but also for any other non-discoverable hardware we currently poke into drivers/platform or arch/x86/platform etc. Yours, Linus Walleij Yours, Linus Walleij
