Help text

If you say yes here you get support for the NXP PCF2127/29/31 RTC chips with integrated quartz crystal for industrial applications. These chips also have watchdog timer and tamper switch detection features.

PCF2127 has an additional feature of 512 bytes battery backed memory that's accessible using nvmem interface.

This driver can also be built as a module. If so, the module will be called rtc-pcf2127.
