How about: - in dm_init(), after binding, we move on to an auto-probe step - a uclass flag indicates that all devices in that uclass must be probed (that will be useful for PCI) - a way to tell DM to probe all devices in a particular uclass (e.g. a call to dm_set_uclass_autoprobe(enum uclass_id, bool) (that will be useful for this serial case) Regards, Simon _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
