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. 15 16 config RTC_PCF2127 17 bool "Enable PCF2127 driver" 18 depends on DM_RTC 19 help 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. 25 26 config RTC_DS1307 27 bool "Enable DS1307 driver" 28 depends on DM_RTC 29 help 30 Support for Dallas Semiconductor (now Maxim) DS1307 and DS1338/9 and 31 compatible Real Time Clock devices. 32 33 config RTC_ISL1208 34 bool "Enable ISL1208 driver" 35 depends on DM_RTC 36 help 37 The Renesas (formerly Intersil) ISL1208 is a I2C Real Time Clock (RTC) and 38 calendar with automatic leap year correction, 2-byte battery backed SRAM, 39 automatic power switch-over, alarm function and 15 selectable frequency 40 outputs. 41 42 This driver supports reading and writing the RTC/calendar and detects 43 total power failures. 44 45 config RTC_RX8010SJ 46 bool "Enable RX8010SJ driver" 47 depends on DM_RTC 48 help 49 Support for Epson RX8010SJ Real Time Clock devices. 50 51 config RTC_MV 52 bool "Enable Marvell RTC driver" 53 depends on DM_RTC 54 help 55 Enable Marvell RTC driver.
