# # 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 SPL_DM_RTC bool "Enable Driver Model for RTC drivers in SPL" depends on SPL_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 TPL_DM_RTC bool "Enable Driver Model for RTC drivers in TPL" depends on TPL_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_PL031 bool "Enable ARM AMBA PL031 RTC driver" help The ARM PrimeCell Real Time Clock (PL031) is an optional SoC peripheral based on the Advanced Microcontroller Bus Architecture (AMBA). It is emulated in QEMU virtual ARM machines. 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. config RTC_MC146818 bool "Enable MC146818 driver" help This is a widely used real-time clock chip originally by Motorola and now available from NXP. It includes a battery-backed real-time clock with a wide array of features and 50 bytes of general-purpose, battery-backed RAM. The driver supports access to the clock and RAM. endmenu
