5. thermal_emergency_poweroff
=============================
On an event of critical trip temperature crossing. Thermal framework
allows the system to shutdown gracefully by calling orderly_poweroff().
In the event of a failure of orderly_poweroff() to shut down the system
we are in danger of keeping the system alive at undesirably high
temperatures. To mitigate this high risk scenario we program a work
queue to fire after a pre-determined number of seconds to start
an emergency shutdown of the device using the kernel_power_off()
function. In case kernel_power_off() fails then finally
emergency_restart() is called in the worst case.
On an event of critical trip temperature crossing the thermal framework
shuts down the system by calling hw_protection_shutdown(). The
hw_protection_shutdown() first attempts to perform an orderly shutdown
but accepts a delay after which it proceeds doing a forced power-off
or as last resort an emergency_restart.
The delay should be carefully profiled so as to give adequate time for
orderly_poweroff(). In case of failure of an orderly_poweroff() the
emergency poweroff kicks in after the delay has elapsed and shuts down
the system.
orderly poweroff.
If set to 0 emergency poweroff will not be supported. So a carefully
profiled non-zero positive value is a must for emergency poweroff to be
triggered.
If the delay is set to 0 emergency poweroff will not be supported. So a
carefully profiled non-zero positive value is a must for emergency
poweroff to be triggered.

*
* @name: The visible name for the IRQ
* @fatal_cnt: If this IRQ is used to signal HW damaging condition it may be
* best to shut-down regulator(s) or reboot the SOC if error
* handling is repeatedly failing. If fatal_cnt is given the IRQ
* handling is aborted if it fails for fatal_cnt times and die()
* callback (if populated) or BUG() is called to try to prevent
* further damage.
* @reread_ms: The time which is waited before attempting to re-read status
* at the worker if IC reading fails. Immediate re-read is done
* if time is not specified.
* @irq_off_ms: The time which IRQ is kept disabled before re-evaluating the
* status for devices which keep IRQ disabled for duration of the
* error. If this is not given the IRQ is left enabled and renable
* is not called.
* @skip_off: If set to true the IRQ handler will attempt to check if any of
* the associated regulators are enabled prior to taking other
* actions. If no regulators are enabled and this is set to true
* a spurious IRQ is assumed and IRQ_NONE is returned.
* @high_prio: Boolean to indicate that high priority WQ should be used.
* @data: Driver private data pointer which will be passed as such to
* the renable, map_event and die callbacks in regulator_irq_data.
* @die: Protection callback. If IC status reading or recovery actions
* fail fatal_cnt times this callback or BUG() is called. This
* callback should implement a final protection attempt like
* disabling the regulator. If protection succeeded this may
* return 0. If anything else is returned the core assumes final
* protection failed and calls BUG() as a last resort.
* @map_event: Driver callback to map IRQ status into regulator devices with
* events / errors. NOTE: callback MUST initialize both the
* errors and notifs for all rdevs which it signals having
* active events as core does not clean the map data.
* REGULATOR_FAILED_RETRY can be returned to indicate that the
* status reading from IC failed. If this is repeated for
* fatal_cnt times the core will call die() callback or BUG()
* as a last resort to protect the HW.
* @renable: Optional callback to check status (if HW supports that) before
* re-enabling IRQ. If implemented this should clear the error
* flags so that errors fetched by regulator_get_error_flags()
* are updated. If callback is not implemented then errors are
* assumed to be cleared and IRQ is re-enabled.
* REGULATOR_FAILED_RETRY can be returned to
* indicate that the status reading from IC failed. If this is
* repeated for 'fatal_cnt' times the core will call die()
* callback or BUG() as a last resort to protect the HW.
* Returning zero indicates that the problem in HW has been solved
* and IRQ will be re-enabled. Returning REGULATOR_ERROR_ON
* indicates the error condition is still active and keeps IRQ
* disabled. Please note that returning REGULATOR_ERROR_ON does
* not retrigger evaluating what events are active or resending
* notifications. If this is needed you probably want to return
* zero and allow IRQ to retrigger causing events to be
* re-evaluated and re-sent.
