  11           Enable drver model for real-time-clock drivers. The RTC uclass
  12           then provides the rtc_get()/rtc_set() interface, delegating to
  13           drivers to perform the actual functions. See rtc.h for a
  14           description of the API.

  20           The PCF2127 is a CMOS Real Time Clock (RTC) and calendar with an integrated
  21           Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz
  22           crystal optimized for very high accuracy and very low power consumption. The PCF2127
  23           has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a
  24           programmable watchdog function, a timestamp function, and many other features.
