Hardware characterization has shown that a new CPR aging RO
scaling factor is required on MSMCOBALT v2. Change this value
to match characterization results. Also specify a CPR count
repeat value of 1 to override the implicit 0 default in order
to improve CPR closed-loop voltage settling stability.

trace_sched_update_task_ravg relies on NULL pointers to ensure that
it doesn't access them. Make sure that when a task exits, these
pointers are set to NULL. Otherwise any call to update_task_ravg()
between sched_exit() and releasing the task structure will access
bogus pointers. In some cases those memory locations are unmapped
and cause a kernel panic.

When system timeouts to pull register state, we do wsi error
recovery, which causes an AHB bus hang. Fix this by doing top

Enable VDD_GFX CPR aging adjustments for MSMCOBALTv2 parts with
CPR fusing revision greater than or equal to 2. At most 15 mV
can be added onto the open-loop and closed-loop voltage as a
result of an aging measurement at runtime. This maximum 15 mV
adjustment was previously accounted for in the fixed open-loop
and closed-loop voltage adjustments. Therefore, remove 15 mV
from both the open-loop and closed-loop voltage adjustments for
all corners.

WCD9335 codec has single master clock supply widget for both
playback and recording paths. Adding separate clock supply
for playback and recording paths will help handle low power
audio recording usecases without affecting playback usecases.
Change is to enable separate clock supply widgets for playback
and recording paths.

Currently, nominal capacity is stored back to the actual capacity
only when the actual capacity is non-zero. However, that can be
true when the battery is inserted for the first time. This makes
the actual capacity to be stored only when a capacity learning
cycle completes. Other algorithms like to use actual capacity
before that. Fix it.

It is possible that normal CFS latencies in the presence of
very heavy task load causes timer migration to be delayed
in hotplug paths. This may in turn prevent the watchdog kthread
from waking up, resulting in a bark.
Technically the watchdog is supposed to be a last-resort
failure recovery; even in this stressful hotplug scenario
the device is *usable*, just incredibly slow. It is arguable
that the watchdog should not have fired in this case, and
the petting mechanism should handle this scenario.
Move the timer to a deferrable timer base. We are really not
using the "deferrable" aspect of the timer, but the fact that
we (msm) also changed deferrable timers to run on any CPU.
This underlying change will allow the watchdog timer to be
handled on any CPU.
This completely depends on the fact that we don't have to
pet the watchdog when *all* CPUs go idle, which would
make sense from a power perspective anyway.

Currently, smb2 charger is configured to not end the charging
cycle when battery overvoltage occurs. However, when the battery
overvoltage status is read, it will be displayed through health
property. Improve this by reading the battery voltage and check
whether it is within 40mV headroom above float voltage. If it is
above that threshold then continue with displaying overvoltage
status.
