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.
