| 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. |
