usb: pd: Don't suspend charging unless changing voltages
To optimize charging during power negotiation and the voltage
is not changing, for example when transitioning from implicit
contract to the default 5V PDO, there is no requirement to
suspend the charging and hence setting the charger's
PROP_PD_CURRENT_MAX can be avoided. It is only needed when
changing voltages, in which case current limit should be
calculated based on pSnkStdby (2.5W), or when staying at the
same voltage and decreasing current.
Also fix the incorrect setting of PROP_CURRENT_MAX to
PROP_PD_CURRENT_MAX when doing a sink->source swap.

sched/hmp: Enhance co-location and scheduler boost features
The recent introduction of the schedtune cgroup controller has provided
the scheduler with added flexibility in terms of some of it's placement
features. In particular each cgroup under the schedtune controller can
now specify:
1) Whether it needs co-location along with other cgroups
2) Whether it is eligible for scheduler boost (sched_boost_enabled)
3) Whether the kernel can override the boost eligibility when necessary
(sched_boost_no_override)
The scheduler now creates a reserved co-location group at boot. This
group is used to co-locate all tasks that form part of any one of the
cgroups that have co-location enabled. This reserved group can neither
be destroyed nor reused for other purposes. Furthermore, cgroups are
only allowed to indicate their co-location preference once at boot.
Further updates are disallowed.
Since we are now creating co-location groups for an extended period of
time, there are a few other factors to consider when determining the
preferred cluster for the group. We first exclude any tasks in the
group that have not been observed to be running for a significant
amount of time. Secondly we introduce the notion of group up and down
migrate tunables to allow different migration policies than individual
tasks. Lastly we break co-location if a single task in a group exceeds
up-migrate but the total load of the group does not exceed group
up-migrate.
In terms of sched_boost, the scheduler now supports multiple types of
boost. These are:
1) FULL_THROTTLE : Force up-migrate tasks belonging any cgroup that
has the sched_boost_enabled flag turned on. Little
CPUs will only be used when big CPUs can no longer
accommodate tasks. Also up-migrate all RT tasks.
2) CONSERVATIVE : Override the sched_boost_enabled flag for all cgroups
except those that have the sched_boost_no_override
flag set. Force up-migrate all tasks belonging to only
those cgroups that still remain eligible for boost.
RT tasks do not get force up migrated.
3) RESTRAINED : Start frequency aggregation for co-located tasks. This
type of boost does not force up-migrate any task.
Finally the boost API removes ref-counting. This means that there can
only be a single entity using boost at any given time. If multiple
entities are managing boost, they are required to be well behaved so
that they don't interfere with one another. Even for a single client,
it is not possible to switch directly from one boost type to another.
Boost must be first turned off before switching over to a new type.

sched: revise boost logic when boost_type is SCHED_BOOST_ON_BIG
At present HMP scheduler boost tends to pack tasks by taking into
account of power cost and cstate. This is suboptimal to performance
as it can lead preemption and higher latency.
Revise logic to prefer the least loaded CPU among the big cluster CPUs
when boost type is SCHED_BOOST_ON_BIG. New logic still honor the
behaviour that scheduler can place tasks on the little CPUs when the
big CPUs are all overcommitted.
Also, it's found that need_idle with boost can easily return previous
CPU when there is no idle CPU found. Fix this issue by making
need_idle flag to take precedence over sched_boost.

sched: Remove thread group iteration from colocation
Iterating a leader task's thread group in order to add them to a
colocation group involves a complex locking chain that ends up
causing a deadlock. The deadlock is as follows when the same task
is being referenced on three different CPUs:
----- ------ -----
CPU 0 CPU 1 CPU 2
----- ------ -----
add_task_to_group(p)
__schedule(prev = p) write_lock( ttwu(p)
related_thread_grp_lock)
lock(pi_lock)
idle_balance() wait for
p->on_cpu
load_balance() unable to acquire
p->pi_lock
send_notification()
wait for read_lock(
related_thread_grp_lock)
unable to set p->on_cpu
There are a couple of ways to resolve this deadlock in the kernel,
however, they are not trivial. For the sake of simplicity, move
the responsibility of thread group iteration back to userspace. This
would apply to both adding and removing the leader task from a
colocation group. The kernel would continue to automatically add
newly forked children of the colocated leader to the colocation
group.
This still leaves an issue with the locking order of the pi_lock and
the related_thread_group_lock. To solve all deadlocks, we need to avoid
taking the pi_lock in reset_all_task_stats() and instead rely on a more
heavy handed approach of taking all rq locks. The pi_lock was taken to
avoid a race between reset_all_task_stats() and sched_exit(). The race
can be avoided with rq locks as well.
