Storm watch provides a simple API for tracking the occurrence of event
storms.
An event storm is defined as a cluster of events where there are
X events with no more than Y milliseconds between them, where X and Y
are configurable per event.
Querying whether a storm has occurred marks a new event.

CC_OUT is the signal/status to the PD that indicates which of
the CC line is active. When its low CC1 is active and when
high CC2 is active.
During Source -> Sink Power Role Swap, CC_OUT is reset default
low (CC1 = CC) when SW sets the UFP/SNK_EN_CMD bit, losing the
plug orientation info and causing USB PD message error if CC2
was the CC pin.
Fix this by ensuring that s/w overrides the CC_OUT signal to
reflect the actual one, in preparation for a possible upcoming
power

Reschedule the idle work in case transition to idle state is rejected
because the GPU is busy. This change avoids the condition where
transition to NAP state gets rejected due to a pending IRQ which is
currently getting served by IRQ handler because of which GPU remains
in active state even when GPU is idle.

BCL gets the state of charge(soc) from the BMS power supply, which will
not capture the HLOS overidden soc value. This can create a scenario
where the mitigation will not be released if the soc value is
overridden in HLOS.
Use the battery supply notification, which can get the state of charge
value from the BMS or the HLOS overridden soc value if present.

"int" type is used to hold the time difference between the successive
updates to nr_run in sched_update_nr_prod(). This can result in
overflow, if the function is called ~2.15 sec after it was called
before. The most probable scenarios are when CPU is idle and
hotplugged. But as we update the last_time of all possible CPUs in
sched_get_nr_running_avg() periodically from a deferrable timer context
(core_ctl module), this overflow is observed only when the system is
completely idle for long time. When this overflow happens we hit
a BUG_ON() in sched_get_nr_running_avg().
Use "u64" type instead of "int" for holding the time difference and
add additional BUG_ON() to catch the instances where sched_clock()
returns a backward value.

The HMP scheduler has two types of task placement boost policies.
(1) boost-on-big policy make use of all big CPUs up to their full capacity
before using the little CPUs. This improves performance on true b.L systems
where the big CPUs have higher efficiency compared to the little CPUs.
(2) boost-on-all policy place the tasks on the CPU having the highest
spare capacity. This policy is optimal for SMP like systems.
The scheduler sets the boost policy to boost-on-big on systems which has
CPUs of different efficiencies. However it is possible that CPUs of the
same micro architecture to have slight difference in efficiency due to
other factors like cache size. Selecting the boost-on-big policy based
on relative difference in efficiency is not optimal on such systems.
The boost-policy device tree property is introduced to specify the
required boost type and it overrides the default selection of boost
type in the scheduler. The possible values for this property are
"boost-on-big" and "boost-on-all".

The current policy has a preference to select an idle CPU in the waker
cluster compared to the waker CPU running only 1 task. By selecting
an idle CPU, it eliminates the chance of waker migrating to a
different CPU after the wakee preempts it. This policy is also not
susceptible to the incorrect "sync" usage i.e the waker does not
goto sleep after waking up the wakee.
However LPM exit latency associated with an idle CPU outweigh the
above benefits on some targets. So add a knob to prefer the waker
CPU having only 1 runnable task over idle CPUs in the waker cluster.

When cycle_counter is used to estimate the frequency, calling

The above bug is hit from __schedule() when next == prev. There
is no need to call update_task_ravg() twice for PUT_PREV_TASK
and PICK_NEXT_TASK events for the same task. Calling
update_task_ravg() with TASK_UPDATE event is sufficient.
