Generic RTC class support. If you say yes here, you will
|
|
be allowed to plug one or more RTCs to your system. You will
|
|
probably want to enable one of more of the interfaces below.
|
|
|
|
This driver can also be built as a module. If so, the module
|
|
will be called rtc-class.

If you say yes here, the system time will be set using
|
|
the value read from the specified RTC device. This is useful
|
|
in order to avoid unnecessary fschk runs.

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.
