Wentong Wu ac2b117acd power: policy: recover deep sleep states from residency policy. ... Commit c248cdf17e remove deep sleep states from residency policy based on SoC loses context in deep sleep states to avoid a "forever timeout" power-off the whole system. It's right if deep sleep means power off whole system only. One of deep sleep states is that most power domains are shut off, but except a few that retain just enough logic to allow the CPU to resume from the same point of execution where it went to sleep. This is well documented and implementations also have same behavior. For another deep sleep state, system off, sys_pm_ctrl_disable_state can prevent system off unexpectedly from being entered on long timeout. And sys_pm_force_power_state can help power off whole system. This reverts commit c248cdf17e. Signed-off-by: Wentong Wu <wentong.wu@intel.com>		2020-01-26 11:13:22 -08:00
