The RTC driver component provides access to the CMOS RTC on x86 via
|
|
the Rtc session. On base-linux 'gettimeofday' is used.
|
|
|
|
The component will use the content of the 'set_rtc' ROM if the
|
|
'allow_setting_rtc' attribute in the 'config' node is set to 'yes'
|
|
to allow setting the RTC. A valid ROM must contain a top node with
|
|
the following attributes:
|
|
|
|
* 'year' (e.g. 2019)
|
|
* 'month' (1 - 12)
|
|
* 'day' (1 - 31)
|
|
* 'hour' (0 - 23)
|
|
* 'minute' (0 - 59)
|
|
* 'second' (0 - 59)
|
|
|
|
The same attributes can be set in the configuration node of the driver
|
|
to initially set the RTC to the givven value.
|
|
|
|
The component will always use 24H mode and relies on the BIOS/firmware
|
|
to do the right thing regarding the year.
