| 93 | If you say yes here you get support for the |
| 94 | RTC test driver. It's a software RTC which can be |
| 95 | used to test the RTC subsystem APIs. It gets |
| 96 | the time from the system clock. |
| 97 | You want this driver only if you are doing development |
| 98 | on the RTC subsystem. Please read the source code |
| 99 | for further details. |

| 101 | This driver can also be built as a module. If so, the module |
