16 Generic RTC class support. If you say yes here, you will
17 be allowed to plug one or more RTCs to your system. You will
18 probably want to enable one of more of the interfaces below.

20 This driver can also be built as a module. If so, the module
21 will be called rtc-class.

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

153 help
154 If you say yes here you get support for the
155 RTC test driver. It's a software RTC which can be
156 used to test the RTC subsystem APIs. It gets
157 the time from the system clock.
158 You want this driver only if you are doing development
159 on the RTC subsystem. Please read the source code
160 for further details.
