2 # RTC drivers configuration
8 bool "Enable Driver Model for RTC drivers"
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.
17 bool "Enable PCF2127 driver"
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.
27 bool "Enable DS1307 driver"
30 Support for Dallas Semiconductor (now Maxim) DS1307 and DS1338/9 and
31 compatible Real Time Clock devices.
34 bool "Enable S35392A driver"
37 Enable s35392a driver which provides rtc get and set function.
