| 33 | The RTC device that will be used to (re)initialize the system |

| 35 | starts up, and when it resumes from a low power state. This |

| 37 | timezone correction. |
| 38 | |
| 39 | The driver for this RTC device must be loaded before late_initcall |

| 41 | |
| 42 | This clock should be battery-backed, so that it reads the correct |
