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.

Meng Yi45a01942017-01-09 11:24:51 -070020 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.
