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

description of the API.

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.
