config RTC_DRV_TEST
tristate "Test driver/device"
depends on RTC_CLASS
help
If you say yes here you get support for the
RTC test driver. It's a software RTC which can be
used to test the RTC subsystem APIs. It gets
the time from the system clock.
You want this driver only if you are doing development
on the RTC subsystem. Please read the source code
for further details.
This driver can also be built as a module. If so, the module
will be called rtc-test.

config RTC_DRV_DS1307
tristate "Dallas/Maxim DS1307/37/38/39/40, ST M41T00"
depends on RTC_CLASS && I2C
help
If you say yes here you get support for various compatible RTC
chips (often with battery backup) connected with I2C. This driver
should handle DS1307, DS1337, DS1338, DS1339, DS1340, ST M41T00,
and probably other chips. In some cases the RTC must already
have been initialized (by manufacturing or a bootloader).
The first seven registers on these chips hold an RTC, and other
registers may add features such as NVRAM, a trickle charger for
the RTC/NVRAM backup power, and alarms. This driver may not
expose all those available chip features.
This driver can also be built as a module. If so, the module
will be called rtc-ds1307.

config RTC_DRV_PCF8583
tristate "Philips PCF8583"
depends on RTC_CLASS && I2C
help
If you say yes here you get support for the Philips PCF8583
RTC chip found on Acorn RiscPCs. This driver supports the
platform specific method of retrieving the current year from
the RTC's SRAM. It will work on other platforms with the same
chip, but the year will probably have to be tweaked.
This driver can also be built as a module. If so, the module
will be called rtc-pcf8583.
