Author: loos Date: Mon Jan 12 03:23:16 2015 New Revision: 277042 URL: https://svnweb.freebsd.org/changeset/base/277042
Log: Add support to turn off Beaglebone with poweroff(8) or shutdown(8) -p. To cut off the power we need to start the shutdown sequence by writing the OFF bit on PMIC. Once the PMIC is programmed the SoC needs to toggle the PMIC_PWR_ENABLE pin when it is ready for the PMIC to cut off the power. This is done by triggering the ALARM2 interrupt on SoC RTC. The RTC driver only works in power management mode which means it won't provide any kind of time keeping functionality. It only implements a way to trigger the ALARM2 interrupt when requested.
