This also made me realize we probably don't have module auto-loading for sunxi-rsb either. Both should be doable with Stephen Boyd's "of: device: Export of_device_{get_modalias, uvent_modalias} to modules" patch.

If it is not too invasive, then yes that would be a sensible addition IMHO.

My mistake. It should obviously go through mfd. So take this instead: Acked-By: Sebastian Reichel <sre@kernel.org> -- Sebastian

If I understand you correctly, I already have a patch-set on the ML that does this.

The i2c subsys does not load modules by compatible, only by i2c-id, with e.g. a modalias of: "i2c:axp209". Populate the axp20x_i2c_id[] table with supported ids, so that module auto-loading will work.
