if PLATFORM_EC_RTC
config PLATFORM_EC_CONSOLE_CMD_RTC
bool "Console command: rtc"
help
This command allows getting and setting the current RTC value. The
value is in seconds since the Epoch (midnight on 1/1/70). You can
convert this to a human date on the command line with 'date -u -d @n'
where n is the numeric value. To convert a time to seconds, use:
date -d '1970-01-01 UTC + n seconds'
config PLATFORM_EC_CONSOLE_CMD_RTC_ALARM
bool "Console command: rtc_alarm"
depends on PLATFORM_EC_CONSOLE_CMD_RTC
help
This command supports setting a real-time-clock (RTC) alarm that
causes an interrupt when the timer reaches that point. To set the
alarm:
rtc <sec> [<usec>]
where:
<sec> is the number of seconds since the epoch
<usec> is the optional number of microseconds (fractional seconds)
config PLATFORM_EC_HOSTCMD_RTC
bool "Host command: EC_CMD_RTC_GET_VALUE etc."
depends on PLATFORM_EC_HOSTCMD
help
Enables support for EC_CMD_RTC_GET_VALUE, EC_CMD_RTC_SET_VALUE,
EC_CMD_RTC_GET_ALARM and EC_CMD_RTC_SET_ALARM which colectively allow
the AP to control the EC's real-time-clock. The AP typically makes
use of the EC's RTC to avoid needing a discrete RTC chip on the board.
