We don't have to define an extra config symbol, IS_REACHABLE does
what we need. And having this config symbol just to save the few
bytes of hwmon support on non-DS3231 chips isn't worth it IMO
(especially as the symbol is set per default).

This driver can also be built as a module. If so, the module
will be called rtc-ds1307.
-config RTC_DRV_DS1307_HWMON
- bool "HWMON support for rtc-ds1307"
- depends on RTC_DRV_DS1307 && HWMON
- depends on !(RTC_DRV_DS1307=y && HWMON=m)
- default y
- help
- Say Y here if you want to expose temperature sensor data on
- rtc-ds1307 (only DS3231)
-
config RTC_DRV_DS1307_CENTURY
bool "Century bit support for rtc-ds1307"
depends on RTC_DRV_DS1307
