A couple of *very* minor points below, otherwise this looks OK to me.
Thankyou for the review.

You have a struct device in the config and the regmap API has
dev_get_regmap() which for most devices that don't have multiple regmaps
will give the right regmap. It would be nice to support this as a
convenience for users.
Yes, sure that makes sense, I will give it a try.
I did try your suggestion, by which I could remove the regmap from
config. One thing I did not like was eeprom-core getting size/stride
info directly from providers and regmap from regmap apis. I was
wondering if we could take a step further and introduce new regmap
helpers like
regmap_get_size(regmap)
regmap_get_stride(regmap)
Which would be give eeprom-core the size and stride info, doing this way
would cut down regmap related things from eeprom_config structure to
minimal and also the source of information would come from just regmap apis.

...

Don't you need a kfree() if device_add() fails?
I will fix it in next version.
