As far as I can see, REGMAP defaults to Y when REGMAP_I2C is selected.
Can you explain more in details why you have to select it explicitely ?
If there is something wrong with the logic, then the logic should be
fixed instead of just adding a selection of REGMAP for that particular
RTC_DRV_DS1307. Because others like RTC_DRV_ABB5ZES3 or RTC_DRV_ABEOZ9
might have the exact same problem.
