Hotplug initialization will trigger a hotplug if temperature stays above
the trip threshold and will try to online if temperature is below the
clear threshold. Since KTM does boot mitigation till thermal-engine is
running, hotplug init can be called twice. First from post init script
and second when the hotplug task is initialized. There is a possiblity
the first init call can set the hotplug local mask and the second init
call wont clear or update the mask with correct value if the temperature
is between the hotplug trip and clear threshold.
Update the hotplug init API to perform the check only if the hotplug
task is initialized. Also the hotplug check will clear the hotplug local
mask if the temperature is not above the trip threshold.

The BTM (Battery temperature module) peripheral driver
on the PMIC (Power management IC) supports threshold
monitoring and notifies clients when thresholds are crossed.
PMCOBALT supports refreshed BTM peripheral register interface
and the driver uses compatible property qpnp-adc-tm-hc to
distinguish using the refreshed peripheral. The external
client interface with the driver remains the same. Updates
include handling the interrupt when the thresholds are
crossed,programming the threholds and configuring
the hardware based on the refreshed design.
BTM peripheral needs the VADC_HC peripheral to compute the
gain/offset that are used to reverse compute the threhold
values to ADC code. Some of the reverse computation API's
such as calculating thermistor thresholds require the
gain and offset values before computing the ADC code to
be programmed. This requires modification to the existing
calibration API in the VADC_HC driver to calculate
the reference calibration points and store these values
for clients to use in the reverse computation

The Limits Management Hardware (LMH-DCVS) is a hardware block for
monitoring thermal profiles and taking immediate action to control
temperature without software intervention. The h/w block can only be
configured under secure mode.
The LMH-DCVS block reads CPU temperatures of a cluster by sensing
information from the TSENS hardware and determines the course of action.
When enabled, the h/w triggers when the high threshold is hit for any
CPU in the cluster. The mitigative action is frequency and voltage
control that is provided to the OSM hardware.
The driver registers a virtual thermal zone device for each hardware
instance. The thermal zone device is used to set the thresholds for the
hardware to work on. Once the thresholds are setup and the trip type is
enabled, the hardware functions autonomously. Mitigative action is
completely controlled in the h/w.
Writing to the actual hardware is done through the SCM call.

Thermal: initialize thermal zone device correctly
After thermal zone device registered, as we have not read any
temperature before, thus tz->temperature should not be 0,
which actually means 0C, and thermal trend is not available.
In this case, we need specially handling for the first
thermal_zone_device_update().
Both thermal core framework and step_wise governor is
enhanced to handle this. And since the step_wise governor
is the only one that uses trends, so it's the only thermal
governor that needs to be updated.

Debug data read was not handling the buffer overflow case when
the data to write is greater than PAGE_SIZE. This resulted in
calling the hardware for new data multiple times.
Returning success when buffer overflowed will cause the sequence
traverse function to call again with a new buffer with increased
size. This process will go on until the buffer size is big enough
to hold the data. But limits data read function couldn't distinguish
if the call is a retry or a new call and will initiate a new data
fetch from hardware and re-populate with new data.
Modify debug read interface to immediately return success when
overflow happens. The debug read function now can distinguish between
a sequence retry call by retaining the data buffer in a static if
overflow happens. When called again, debug read now will avoid
calling the hardware for new data and instead will populate the new
sequence buffer with the previously fetched data.

Threshold list will be read in interrupt context. Using
a lock in the interrupt context is not acceptable, but the
list traversal needs to be protected. Because the threshold
list can be updated with a new threshold or an existing
threshold can be removed. Doing a list traversal during the
list mutation may result in unassigned memory access
violation. Use of list_for_each_entry_safe() function for
traversing, won't help. Because this function can help
only if the traversal loop removes the current element, that
is pointed by this iteration.
Use rcu to ensure a safe list traversal without a lock.
Addition or deletion to the threshold list is an infrequent
operation when compared to the threshold list read, which
happens when temperature threshold trips. Using rcu ensures
that read operations are done faster without getting
blocked by a lock and the list write operations are done
in a list safe fashion. Replace the list_for_each_entry_safe()
function with rcu safe list traversal function
list_for_each_entry_rcu(), wherever it is applicable.
