| 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. | |
| 19 | ||
| 20 | This driver can also be built as a module. If so, the module | |
| 21 | will be called rtc-class. | |

| 27 | help | |
| 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. | |
