2 # RTC drivers configuration
8 bool "Enable Driver Model for RTC drivers"
11 Enable drver model for real-time-clock drivers. 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.
17 bool "Enable Driver Model for RTC drivers in SPL"
20 Enable drver model for real-time-clock drivers. The RTC uclass
21 then provides the rtc_get()/rtc_set() interface, delegating to
22 drivers to perform the actual functions. See rtc.h for a
23 description of the API.
26 bool "Enable Driver Model for RTC drivers in TPL"
29 Enable drver model for real-time-clock drivers. The RTC uclass
30 then provides the rtc_get()/rtc_set() interface, delegating to
31 drivers to perform the actual functions. See rtc.h for a
32 description of the API.
35 bool "Enable PCF2127 driver"
38 The PCF2127 is a CMOS Real Time Clock (RTC) and calendar with an integrated
39 Temperature Compensated Crystal (Xtal) Oscillator (TCXO) and a 32.768 kHz quartz
40 crystal optimized for very high accuracy and very low power consumption. The PCF2127
41 has a selectable I2C-bus or SPI-bus, a backup battery switch-over circuit, a
42 programmable watchdog function, a timestamp function, and many other features.
45 bool "Enable DS1307 driver"
48 Support for Dallas Semiconductor (now Maxim) DS1307 and DS1338/9 and
49 compatible Real Time Clock devices.
52 bool "Enable ISL1208 driver"
55 The Renesas (formerly Intersil) ISL1208 is a I2C Real Time Clock (RTC) and
56 calendar with automatic leap year correction, 2-byte battery backed SRAM,
57 automatic power switch-over, alarm function and 15 selectable frequency
60 This driver supports reading and writing the RTC/calendar and detects
64 bool "Enable RV3029 driver"
67 The MicroCrystal RV3029 is a I2C Real Time Clock (RTC) with 8-byte
70 This driver supports reading and writing the RTC/calendar and the
71 battery-baced SRAM section.
74 bool "Enable RV8803 driver"
77 The Micro Crystal RV8803 is a high accuracy, ultra-low power I2C
78 Real Time Clock (RTC) with temperature compensation.
80 This driver supports reading and writing the RTC/calendar and
81 detects total power failures.
84 bool "Enable RX8010SJ driver"
87 Support for Epson RX8010SJ Real Time Clock devices.
90 bool "Enable ARM AMBA PL031 RTC driver"
92 The ARM PrimeCell Real Time Clock (PL031) is an optional SoC
93 peripheral based on the Advanced Microcontroller Bus Architecture
94 (AMBA). It is emulated in QEMU virtual ARM machines.
97 bool "Enable Marvell RTC driver"
100 Enable Marvell RTC driver. This driver supports the rtc that is present
101 on some Marvell SoCs.
104 bool "Enable S35392A driver"
107 Enable s35392a driver which provides rtc get and set function.
110 bool "Enable MC146818 driver"
112 This is a widely used real-time clock chip originally by Motorola
113 and now available from NXP. It includes a battery-backed real-time
114 clock with a wide array of features and 50 bytes of general-purpose,
115 battery-backed RAM. The driver supports access to the clock and RAM.
118 bool "Enable M41T62 driver"
120 Enable driver for ST's M41T62 compatible RTC devices (like RV-4162).
121 It is a serial (I2C) real-time clock (RTC) with alarm.
