I do not have any sensor attached, the goal is to build a generic kernel, and people can use overlays or patch their device tree to add support for additional devices. In that regard, I have the impression that csi2rx device (and maybe the camss device?) should not be marked as enabled in the default device tree. I think they could be enabled by users as part of the change need to add the sensor node. Regards Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@xxxxxxxxxxx http://aurel32.net
