| 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_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_RX8010SJ | |

| 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. | |
| 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. | |
