24 | If you say yes here, the system time (wall clock) will be set using |
25 | the value read from a specified RTC device. This is useful to avoid | |

7ca1d488 | 33 | The RTC device that will be used to (re)initialize the system |
ae64d169 AZ |
34 | clock, usually rtc0. Initialization is done when the system |
35 | starts up, and when it resumes from a low power state. This | |
779d2089 DB |
36 | device should record time in UTC, since the kernel won't do |
37 | timezone correction. | |
7ca1d488 | 38 | |
55ff1aba DB |
39 | The driver for this RTC device must be loaded before late_initcall |
40 | functions run, so it must usually be statically linked. | |
41 | ||
7ca1d488 | 42 | This clock should be battery-backed, so that it reads the correct |
ae64d169 | 43 | time when the system boots from a power-off state. Otherwise, your |
7ca1d488 DB |
44 | system will need an external clock source (like an NTP server). |
45 | ||
46 | If the clock you specify here is not battery backed, it may still | |
47 | be useful to reinitialize system time when resuming from system | |
09b6bdb3 | 48 | sleep states. Do not specify an RTC here unless it stays powered |
7ca1d488 | 49 | during all this system's supported sleep states. |
