menu "Real Time Clock"
config DM_RTC
bool "Enable Driver Model for RTC drivers"
depends on DM
select LIB_DATE
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_ENABLE_32KHZ_OUTPUT
bool "Enable RTC 32Khz output"
help
Some real-time clocks support the output of 32kHz square waves (such as ds3231),
the config symbol choose Real Time Clock device 32Khz output feature.
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_DS3232
bool "Enable DS3232 driver"
depends on DM_RTC
depends on DM_I2C
help
Support for Dallas Semiconductor (now Maxim) DS3232 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_RV3029
bool "Enable RV3029 driver"
depends on DM_RTC
help
The MicroCrystal RV3029 is a I2C Real Time Clock (RTC) with 8-byte
battery-backed SRAM.
This driver supports reading and writing the RTC/calendar and the
battery-baced SRAM section.
config RTC_RV8803
bool "Enable RV8803 driver"
depends on DM_RTC
help
The Micro Crystal RV8803 is a high accuracy, ultra-low power I2C
Real Time Clock (RTC) with temperature compensation.
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_RX8025
bool "Enable RX8025 driver"
help
Support for Epson RX8025 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

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.
config RTC_M41T62
bool "Enable M41T62 driver"
help
Enable driver for ST's M41T62 compatible RTC devices (like RV-4162).
It is a serial (I2C) real-time clock (RTC) with alarm.
config RTC_STM32
bool "Enable STM32 RTC driver"
depends on DM_RTC
help
