AM335X SoCs support power-off via a power management chip (PMIC). An alarm in the real time clock is used to trigger the PMIC to cut the power. To ensure the alarm goes off when the system is in a safe state, the RTC is frozen when the alarm is set. At the last moment, the kernel unfreezes the RTC to let the alarm go off. This patch adds a mini driver for unfreezing the RTC as well as code to handle RBT_POWEROFF on Minix/arm. Change-Id: I7d48e75791e3a81bdd2f7704997193a269409fe8
