This was due to the rtc-ds1307 module not > exporting an of_match table, and not yet having Javier's "report OF style > modalias when probing using DT" [0] patch applied What I didn't get here: did your version of the RTC driver use probe() or probe_new() without i2c_device_id table or did you try both? I assume module autoloading only fails with probe_new(), otherwise we would be in serious trouble. But I'd wonder then that userspace instantiation works. Thanks to you and Javier for the testing. I pushed the patches to a local branch for now and will merge once this question is clear. Regards, Wolfram
