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 RX8010SJ driver"
37 Support for Epson RX8010SJ Real Time Clock devices.
40 bool "Enable S35392A driver"
43 Enable s35392a driver which provides rtc get and set function.
