This flag determines whether the thread should currently
process the work in the thread->todo worklist.
The prime usecase for this is improving the performance
of synchronous transactions: all synchronous transactions
post a BR_TRANSACTION_COMPLETE to the calling thread,
but there's no reason to return that command to userspace
right away - userspace anyway needs to wait for the reply.
Likewise, a synchronous transaction that contains a binder
object can cause a BC_ACQUIRE/BC_INCREFS to be returned to
userspace; since the caller must anyway hold a strong/weak
ref for the duration of the call, postponing these commands
until the reply comes in is not a problem.
Note that this flag is not used to determine whether a
thread can handle process work; a thread should never pick
up process work when thread work is still pending.

Currently, auto calibration will be invoked if an OVP fault is
triggered because of an incorrect sink configuration. However,
there are certain hardware platforms where the display panel is
not used. It is hard to differentiate such platforms as they
will be using the same device tree configuration or parameters
related to display panel passed through the bootloader.
Disable the module permanently and also keep the OVP fault
interrupt disabled when a valid sink configuration is not found
by auto calibration.

As per the hardware documentation, WLED1_CTRL_SWITCHING_FREQUENCY
register is in logic_rb instead of in periph_rb. With overwrite
bit (bit 7) set, this can change the switching frequency from
1.6 MHz to 800 KHz for AMOLED whenever the module is disabled and
enabled. Fix this by not setting the overwrite bit for AMOLED
panel so that the frequency can be selected internally by the
hardware based on EN_AMOLED configuration.

If CABC is enabled and auto calibration is attempted, then OVP
fault can be seen even with a valid sink configuration and a
brightness level greater than or equal to 0.4 % dimming. This is
because of the modulation done through CABC pin which if low
enough can cause the brightness level to still go further down.
Fix this by disabling CABC on all sinks before running auto
calibration and re-enable it if the feature is enabled. Also,
modify the auto calibration brightness level to 200 so that the
load increase on WLED_VOUT can bring the voltage below OVP
threshold quick enough on a valid sink configuration.
Finally, disable WLED module before switching the sink
configuration and enable it after configuring sinks.

The code is to get the CPU util by accumulate different scheduling
classes and when the total util value is larger than CPU capacity
then it clamps util to CPU maximum capacity. So we can get correct util
value when use PELT signal but if with WALT signal it misses to clamp
util value.
On the other hand, WALT doesn't accumulate different class utilization
but it needs to applying boost margin for WALT signal the CPU util
value is possible to be larger than CPU capacity; so this patch is to
always clamp util to CPU maximum capacity.

When multiple worker threads compete to update event_list, with current
vblank_ctrl_worker mechanism, there is one risk which can casue list node
is deleted for twice. This is because, due to the protected scope by
the spin_lock, mutex can exit when one thread is transvering the list,
but another queue thread may continue to add new event to the list.
This brings conflict risk. This patch is to correct this.
