A306a GPU have the two different frequency plans. The frequency
plan needs to be loaded dynamically based on the speed bin
information. Add support for A306a gpu to read the speed bin
information and choose frequency plan dynamically.

There is a race between watchdog being enabled by hotplug and core
isolation disabling the watchdog. When a CPU is hotplugged in and
the hotplug lock has been released the watchdog thread might not
have run yet to enable the watchdog. We have to wait for the
watchdog to be enabled before proceeding.

To move tasks off a cpu when offlining the rq needs to be offlined to
un-throttle tasks. However, tasks might still run on the CPU even after
the CPU has been isolated (per-CPU threads). Thus we should leave the rq
in online state after tasks have been moved.

There is a race condition between checking for whether an active load
balance request has been set and clearing the request. A cpu might have
an active load balance request set and queued but not executed yet.
Before the load balance request is executed the request flag might be
cleared by cpu isolation. Then subsequently the load balancer or tick
might try to do another active load balance. This can cause the same
active load balance work to be queued twice causing report of list
corruption.
Fix this by moving the clearing of the request to the stopper thread and
ensuring that load balance will not try to queue a request on an
already isolated cpu.

The scheduler allocates memory for the task load structures during
fork. It then relies to sched_exit() to be called to free that memory.
However, if the fork itself fails at any point after the allocation,
the memory is left unclaimed forever. Fix this memory leak by freeing
the allocated memory under error conditions.

Task load structure allocations can consume a lot of memory as the
number of tasks begin to increase. Also they might exhaust the atomic
memory pool pretty quickly if a workload starts spawning lots of
threads in a short amount of time thus increasing the possibility of
failed allocations. Move the call to init_new_task_load() outside
atomic context and start using GFP_KERNEL for allocations. There is
no need for this allocation to be in atomic context.

Recent changes to scheduler guided frequency have started reporting
the maximum of the cpu load and the load of the top task on a CPU
to the governor. Use the same information to determine whether a
notification is necessary or not.

Capping load when reporting to the governor was important prior to new
scheduler guided frequency changes as intra-cluster migrations would
sometimes lead to CPU loads well in excess of 100%. With the new top
task approach however, load greater than 100% is no longer possible
except for the same conditions that were previously exempted (i.e.
inter-cluster migrations and frequency aggregation).

Currently, fuel gauge assumes that the battery charging current
is provided only by the main charger. When ESR pulse is needed,
it notifies only the main charger to lower its FCC. However, with
parallel charger also supplying the FCC to the battery, the main
charger can end up increasing its FCC instead of lowering it.
This is because of the fact that FCC of main charger is lower
than the total battery charging current because of the current
distribution to the parallel charger and the code sent by FG
allows it to increase its FCC.
Fix this by controlling ESR FCC current code to 300mA in software
when the device is charging and the parallel charger is enabled.
Switch back to hardware control when the device is not charging
or parallel charger is disabled.

parameter "qcom,chg-inhibit-threshold-mv" through which the
charge inhibit threshold can be configured. If the property is
not specified, then charge inhibit feature is kept disabled.
