That was my first reflex, too, but this is the *board* (fallback) compatible, listed in the root node, so you have to list it here for each SoC, together with the respective blocklist in the next patch. We are doing the same for the H616, and actually also need that for the H618. Weird, I know, but last time I check not easy to fix. Cheers, Andre

Weird, I know, but last time I check not easy to fix. Oh, that's bad. What's the rationale to have so complicated probe method? Why not using standard, compatible based one? Best regards, Jernej
