# # RTC drivers configuration # menu "Real Time Clock" config DM_RTC bool "Enable Driver Model for RTC drivers" depends on DM help 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. config RTC_PCF2127 bool "Enable PCF2127 driver" depends on DM_RTC help 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. config RTC_DS1307 bool "Enable DS1307 driver" depends on DM_RTC help Support for Dallas Semiconductor (now Maxim) DS1307 and DS1338/9 and compatible Real Time Clock devices. config RTC_ISL1208 bool "Enable ISL1208 driver" depends on DM_RTC help The Renesas (formerly Intersil) ISL1208 is a I2C Real Time Clock (RTC) and calendar with automatic leap year correction, 2-byte battery backed SRAM, automatic power switch-over, alarm function and 15 selectable frequency outputs. This driver supports reading and writing the RTC/calendar and detects total power failures. config RTC_RX8010SJ bool "Enable RX8010SJ driver" depends on DM_RTC help Support for Epson RX8010SJ Real Time Clock devices. config RTC_MV bool "Enable Marvell RTC driver" depends on DM_RTC help Enable Marvell RTC driver. This driver supports the rtc that is present on some Marvell SoCs. config RTC_S35392A bool "Enable S35392A driver" select BITREVERSE help Enable s35392a driver which provides rtc get and set function. endmenu
