-         Enable pcf2127 driver which provides rtc get and set function
+         The PCF2127 is a CMOS Real Time Clock (RTC) and calendar with an integrated
+         Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz
+         crystal optimized for very high accuracy and very low power consumption. The PCF2127
+         has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a
+         programmable watchdog function, a timestamp function, and many other features.
