| The RTC device that will be used to (re)initialize the system | |
| clock, usually rtc0. Initialization is done when the system | |
| starts up, and when it resumes from a low power state. This | |
| device should record time in UTC, since the kernel won't do | |
| timezone correction. | |
| The driver for this RTC device must be loaded before late_initcall | |
| functions run, so it must usually be statically linked. | |
| This clock should be battery-backed, so that it reads the correct | |
| time when the system boots from a power-off state. Otherwise, your | |
| system will need an external clock source (like an NTP server). | |
| If the clock you specify here is not battery backed, it may still | |
