Subject: [PATCH 001/135] thermal/intel: Introduce Intel TCC library

There are several different drivers that accesses the Intel TCC
(thermal control circuitry) MSRs, and each of them has its own
implementation for the same functionalities, e.g. getting the current
temperature, getting the tj_max, and getting/setting the tj_max offset.

Introduce a library to unify the code for Intel CPU TCC MSR access.

At the same time, ensure the temperature is got based on the updated
tjmax value because tjmax can be changed at runtime for cases like
the Intel SST-PP (Intel Speed Select Technology - Performance Profile)
level change.

Subject: [PATCH 007/135] thermal/core: Add a generic thermal_zone_get_trip()
 function

The thermal_zone_device_ops structure defines a set of ops family,
get_trip_temp(), get_trip_hyst(), get_trip_type(). Each of them is
returning a property of a trip point.

The result is the code is calling the ops everywhere to get a trip
point which is supposed to be defined in the backend driver. It is a
non-sense as a thermal trip can be generic and used by the backend
driver to declare its trip points.

Part of the thermal framework has been changed and all the OF thermal
drivers are using the same definition for the trip point and use a
thermal zone registration variant to pass those trip points which are
part of the thermal zone device structure.

Consequently, we can use a generic function to get the trip points
when they are stored in the thermal zone device structure.

This approach can be generalized to all the drivers and we can get rid
of the ops->get_trip_*. That will result to a much more simpler code
and make possible to rework how the thermal trip are handled in the
thermal core framework as discussed previously.

This change adds a function thermal_zone_get_trip() where we get the
thermal trip point structure which contains all the properties (type,
temp, hyst) instead of doing multiple calls to ops->get_trip_*.

That opens the door for trip point extension with more attributes. For
instance, replacing the trip points disabled bitmask with a 'disabled'
field in the structure.

Here we replace all the calls to ops->get_trip_* in the thermal core
code with a call to the thermal_zone_get_trip() function.

The thermal zone ops defines a callback to retrieve the critical
temperature. As the trip handling is being reworked, all the trip
points will be the same whatever the driver and consequently finding
the critical trip temperature will be just a loop to search for a
critical trip point type.

Provide such a generic function, so we encapsulate the ops
get_crit_temp() which can be removed when all the backend drivers are
using the generic trip points handling.

While at it, add the thermal_zone_get_num_trips() to encapsulate the
code more and reduce the grip with the thermal framework internals.

Subject: [PATCH 008/135] thermal/sysfs: Always expose hysteresis attributes

Instead of avoiding to expose the hysteresis attributes of a thermal
zone when its get_trip_hyst() operation is not defined, which is
confusing, expose them always and use the default
thermal_zone_get_trip() function returning 0 hysteresis when that
operation is not present.

The hysteresis of 0 is perfectly valid, so this change should not
introduce any backwards compatibility issues.

Subject: [PATCH 009/135] thermal/core: Add a generic thermal_zone_set_trip()
 function

The thermal zone ops defines a set_trip callback where we can invoke
the backend driver to set an interrupt for the next trip point
temperature being crossed the way up or down, or setting the low level
with the hysteresis.

The ops is only called from the thermal sysfs code where the userspace
has the ability to modify a trip point characteristic.

With the effort of encapsulating the thermal framework core code,
let's create a thermal_zone_set_trip() which is the writable side of
the thermal_zone_get_trip() and put there all the ops encapsulation.

Subject: [PATCH 011/135] thermal/of: Use generic thermal_zone_get_trip()
 function

The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.

The thermal OF code uses the thermal_zone_device_register_with_trips()
function. It builds the trips array and pass it to the register
function. That means the get_trip_* ops are duplicated with what does
already the core code.

Remove them.

As all the calls have been replaced by thermal_zone_get_trip(), there

Subject: [PATCH 024/135] thermal/of: Remove of_thermal_set_trip_hyst()

The thermal core is providing the generic thermal_zone_set_trip()
function which does exactly what the OF ops function is doing.

It is pointless to define our own version, just remove the ops and the
thermal_zone_set_trip() will take care of it.

Subject: [PATCH 034/135] thermal/intel/int340x: Replace parameter to simplify

In the process of replacing the get_trip_* ops by the generic trip
points, the current code has an 'override' property to add another
indirection to a different ops.

Rework this approach to prevent this indirection and make the code
ready for the generic trip points conversion.

Actually the get_temp() is different regarding the platform, so it is
pointless to add a new set of ops but just create dynamically the ops
at init time.

Subject: [PATCH 036/135] thermal/drivers/exynos: Fix NULL pointer dereference
 when getting the critical temp

The driver is assuming the get_critical temperature exists as it is
inherited by the thermal of ops. But this one has been removed in
favor of the generic one.

Use the generic thermal_zone_get_crit_temp() function instead

Subject: [PATCH 037/135] thermal/drivers/tegra: Fix crash when getting
 critical temp

Commit 13bea86623be ("thermal/of: Remove of_thermal_get_crit_temp()")
removed the function of_thermal_get_crit_temp() and this is causing a
NULL pointer deference crash when attempting to call the 'get_crit_temp'
function pointer because this function pointer is no longer initialised.
Fix this by replacing the call to the 'get_crit_temp' function pointer
with a call to the function thermal_zone_get_crit_temp() instead.

The get_trip_temp, get_trip_hyst and get_trip_type are handled by the

The set_trip_temp() generic function does some checks which are no

Convert ops content logic into generic trip points and register them

needed and they can be removed.

Convert ops content logic into generic trip points and register them with the
thermal zone.

Subject: [PATCH 042/135] thermal/drivers/qcom: Fix lock inversion

The thermal-zone-device lock is held by core when setting trip points
and the driver takes its chip lock in the corresponding callback.

Fetching the thermal trip points using thermal_zone_get_trip() also
involves taking the thermal-zone-device lock, which means that the chip
lock can not be held when doing so.

Drop the chip lock temporarily during probe to avoid the lock inversion
that was detected by lockdep:

The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL-terminated strings.

Subject: [PATCH 044/135] thermal: intel: Fix unsigned comparison with less
 than zero

The return value from the call to intel_tcc_get_tjmax() is int, which can
be a negative error code. However, the return value is being assigned to
an u32 variable 'tj_max', so making 'tj_max' an int.

Eliminate the following warning:
./drivers/thermal/intel/intel_soc_dts_iosf.c:394:5-11: WARNING: Unsigned expression compared with zero: tj_max < 0

 qcom,adc-tm7

The qcom,adc-tm7 compatible is already used in PMK8350 so add it to the
Qualcomm PMIC Thermal Monitoring ADC.  Based on downstream sources, the
new compatible for TM7 differs from older TM5 by allowing configuring
per sensor decimation, time measurement and number of sample averaging -
unlike one configuration per entire device.  This was not reflected in
the bindings, therefore comment the new compatible as incomplete as it
might change and its ABI is no stable.

When adding support for msm8976 it was thought that msm8956 would reuse
the same compat. However checking the vendor kernel revealed that these
two platforms use different slope values for calculating the calibration
data.

Add new compatible for the tsens on msm8956 SoC.

Allow specifying the exact calibration mode and calibration data as nvmem
cells, rather than specifying just a single calibration data blob.

Note, unlike the vendor kernel the calibration data uses hw_ids rather
than software sensor indices (to match actual tsens usage in
thermal zones).

Subject: [PATCH 052/135] thermal/drivers/tsens: Drop unnecessary hw_ids

The tsens driver defaults to using hw_id equal to the index of the
sensor. Thus it is superfluous to declare such hw_id arrays. Drop such
arrays from mdm9607 and msm8976 data.

Subject: [PATCH 054/135] thermal/drivers/tsens: Sort out msm8976 vs msm8956
 data

Tsens driver mentions that msm8976 data should be used for both msm8976
and msm8956 SoCs. This is not quite correct, as according to the
vendor kernels, msm8976 should use standard slope values (3200), while
msm8956 really uses the slope values found in the driver.

Add separate compatibility string for msm8956, move slope value
overrides to the corresponding init function and use the standard
compute_intercept_slope() function for both platforms.

Subject: [PATCH 056/135] thermal/drivers/tsens: limit num_sensors to 9 for
 msm8939

On msm8939 last (hwid=10) sensor was added in the hw revision 3.0.
Calibration data for it was placed outside of the main calibration data
blob, so it is not accessible by the current blob-parsing code.

Moreover data for the sensor's p2 is not contiguous in the fuses. This
makes it hard to use nvmem_cell API to parse calibration data in a
generic way.

Since the sensor doesn't seem to be actually used by the existing
hardware, disable the sensor for now.

Subject: [PATCH 059/135] thermal/drivers/tsens: Rework legacy calibration data
 parsers

Rework existing calibration parsing code to use simple data structure
describing data layout. This allows us to drop all the mask & shift
values, replacing them with data tables.

The code for msm8974 is not reworked, as it has separate calibration and
backup data.

Subject: [PATCH 063/135] thermal/drivers/qcom: Remove duplicate set next trip
 point interrupt code

The tsens driver reprogram the next trip points in the irq
handler. This function then call thermal_zone_device_update().

However, thermal_zone_device_update() calls thermal_zone_set_trips()
and from there it calls the backend 'set_trips' ops. This one in turn
reprogram the next trip points (low/high).

Consequently, the code setting the next trip points interrupt in the
interrupt handle is not needed and could be removed.

Subject: [PATCH 064/135] thermal/drivers/imx_sc_thermal: Fix the loop
 condition

The minimal resource ID is 0: IMX_SC_R_AP_0=0, so fix
the loop condition. Aside of this - constify the array.

Add iMX8QM sensors. As stated in 31fd4b9db13b ("thermal/drivers/imx_sc:
Rely on the platform data to get the resource id"):

    The thermal OF code returns -ENODEV if the thermal zone registration
    with a specific id fails because the description is not available in
    the DT for such a sensor id. In this case we continue with the other
    ids without bailing out with an error.

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.

Instead of having if-else logic selecting either raw_to_mcelsius_v1 or
raw_to_mcelsius_v2 in mtk_thermal_bank_temperature introduce a function
pointer raw_to_mcelsius to struct mtk_thermal which is initialized in the
probe function.

Brings code to assign values from efuse as well as new function to
convert raw temperature to millidegree celsius, as found in MediaTek's

Subject: [PATCH 081/135] thermal/drivers/armada: Use the
 thermal_zone_get_crit_temp()

The driver browses the trip point to find out the critical trip
temperature. However the function thermal_zone_get_crit_temp() does
already that, so the routine is pointless in the driver.

Use thermal_zone_get_crit_temp() instead of inspecting all the trip
points.

In addition, the hysteresis value is set to zero. A critical trip
point does not have a hysteresis.

Subject: [PATCH 086/135] thermal: intel: intel_pch: Use generic trip points

The thermal framework gives the possibility to register the trip
points along with the thermal zone.  When that is done, no get_trip_*
callbacks are needed and they can be removed.

Convert the existing callbacks content logic into generic trip points
initialization code and register them along with the thermal zone.

In order to consolidate the code, use an ACPI trip library function
to populate a generic trip point.

Subject: [PATCH 088/135] thermal/core: Remove unneeded ida_destroy()

As per documentation for the ida_destroy() function: "If the IDA is
already empty, there is no need to call this function."

The thermal framework is in the init sequence, so the ida was not yet
used and consequently it is empty in case of error.

There is no need to call ida_destroy(), let's remove the calls.

Subject: [PATCH 089/135] thermal/core: Move the thermal trip code to a
 dedicated file

The thermal_core.c files contains a lot of functions handling
different thermal components like the governors, the trip points, the
cooling device, the OF cooling device, etc ...

This organization does not help to migrate to a more sane code where
there is a better self-encapsulation as all the components' internals
can be directly accessed from a single file.

For the sake of clarity, let's move the thermal trip points code in a
dedicated thermal_trip.c file and add a function to browse all the
trip points like we do with the thermal zones, the govenors and the
cooling devices.

The same can be done for the cooling devices and the governor code but
that will come later as the current work in the thermal framework is
to fix the trip point handling and use a generic trip point structure.

No functional changes intended.

Subject: [PATCH 090/135] thermal: Fail object registration if thermal class is
 not registered

If thermal_class is not registered with the driver core, there is no way
to expose the interfaces used by the thermal control framework, so
prevent thermal zones and cooling devices from being registered in
that case by returning an error from object registration functions.

For this purpose, use a thermal_class pointer that will be NULL if the
class is not registered.  To avoid wasting memory in that case, allocate
the thermal class object dynamically and if it fails to register, free
it and clear the thermal_class pointer to NULL.

Subject: [PATCH 091/135] thermal: intel: int340x: Add production mode
 attribute

It is possible that the system manufacturer locks down thermal tuning
beyond what is usually done on the given platform. In that case user
space calibration tools should not try to adjust the thermal
configuration of the system.

To allow user space to check if that is the case, add a new sysfs
attribute "production_mode" that will be present when the ACPI DCFG
method is present under the INT3400 device object in the ACPI Namespace.

Subject: [PATCH 093/135] thermal: ACPI: Initialize trips if temperature is out
 of range

In some cases it is still useful to register a trip point if the
temperature returned by the corresponding ACPI thermal object (for
example, _HOT) is invalid to start with, because the same ACPI
thermal object may start to return a valid temperature after a
system configuration change (for example, from an AC power source
to battery an vice versa).

For this reason, if the ACPI thermal object evaluated by
thermal_acpi_trip_init() successfully returns a temperature value that
is out of the range of values taken into account, initialize the trip
point using THERMAL_TEMP_INVALID as the temperature value instead of
returning an error to allow the user of the trip point to decide what
to do with it.

Also update pch_wpt_add_acpi_psv_trip() to reject trip points with
invalid temperature values.

Subject: [PATCH 094/135] thermal: intel: int340x: Rework updating trip points

It is generally invalid to change the trip point indices after they have
been exposed via sysfs.

Moreover, the thermal objects in the ACPI namespace cannot go away and
appear on the fly.  In practice, the only thing that can happen when the
INT3403_PERF_TRIP_POINT_CHANGED notification is sent by the platform
firmware is a change of the return values of those thermal objects.

For this reason, add a special function for updating the trip point
temperatures after re-evaluating the respective ACPI thermal objects
and change int3403_notify() to invoke it instead of
int340x_thermal_read_trips() that would change the trip point indices
on errors.  Also remove the locking from the latter, because it is only
called before registering the thermal zone and it cannot race with the
zone's callbacks.

Subject: [PATCH 095/135] thermal: intel: int340x: Use zone lock for
 synchronization

Because the ->get_trip_temp() and ->get_trip_type() thermal zone
callbacks are only invoked from __thermal_zone_get_trip() which is
always called by the thermal core under the zone lock, it is sufficient
for int340x_thermal_update_trips() to acquire the zone lock for mutual
exclusion with those callbacks.

Accordingly, modify int340x_thermal_update_trips() to use the zone lock
instead of the internal trip_mutex and drop the latter which is not
necessary any more.

Subject: [PATCH 096/135] thermal: intel: int340x: Use generic trip points
 table

Modify int340x_thermal_zone_add() to register the thermal zone along
with a trip points table, which allows the trip-related zone callbacks
to be dropped, because they are not needed any more.

In order to consolidate the code, use ACPI trip library functions to
populate generic trip points in int340x_thermal_read_trips() and to
update them in int340x_thermal_update_trips().

Subject: [PATCH 097/135] thermal: ACPI: Make helpers retrieve temperature only

It is slightly better to make the ACPI thermal helper functions retrieve
the trip point temperature only instead of doing the full trip point
initialization, because they are also used for updating some already
registered trip points, in which case initializing a new trip just
in order to update the temperature of an existing one is somewhat
wasteful.

Modify the ACPI thermal helpers accordingly and update their users.

No intentional functional impact.

Subject: [PATCH 098/135] thermal: intel: int340x: Assorted minor cleanups

Improve some inconsistent usage of white space in int340x_thermal_zone.c,
fix up one coding style issue in it (missing braces around an else
branch of a conditional) and while at it replace a !ACPI_FAILURE()
check with an equivalent ACPI_SUCCESS() one.

No intentional functional impact.

Subject: [PATCH 099/135] thermal: intel: int340x: Rename variable in
 int340x_thermal_zone_add()

Rename local variables int34x_thermal_zone in int340x_thermal_zone_add()
and int340x_thermal_zone_remove() to int34x_zone which allows a number
of code lines to be shorter and easier to read and adjust some white
space for consistency.

Subject: [PATCH 100/135] thermal: intel: int340x: Drop pointless cast to
 unsigned long

The explicit casting from int to unsigned long in
int340x_thermal_get_zone_temp() is pointless, becuase the multiplication
result is cast back to int by the assignment in the same statement, so
drop it.

No expected functional impact.

Subject: [PATCH 101/135] thermal: intel: int340x: Improve
 int340x_thermal_set_trip_temp()

Instead of using snprintf() to populate the ACPI object name in
int340x_thermal_set_trip_temp(), use an appropriate initializer
and make the function fail if its trip argument is greater than 9,
because ACPI object names can only be 4 characters long and it does
not make sense to even try to evaluate objects with longer names (that
argument is guaranteed to be non-negative, because it comes from the
thermal code that will not pass negative trip numbers to zone
callbacks).

Subject: [PATCH 105/135] thermal: intel: intel_pch: Eliminate device
 operations object

The same device operations object is pointed to by all of the board
configurations in the driver, so effectively the same operations
callbacks are used by all of them which only adds overhead (that can
be significant due to retpolines) for no real purpose.

For this reason, drop the device operations object and replace the
respective callback invocations by direct calls to the specific
functions that were previously pointed to by callback pointers.

No intentional change in behavior.

Subject: [PATCH 106/135] thermal: intel: intel_pch: Fold two functions into
 their callers

Fold two functions, pch_hw_init() and pch_get_temp(), that each have
only one caller, into their respective callers to make the code somewhat
easier to follow.

No intentional functional impact.

Subject: [PATCH 109/135] thermal: intel: intel_pch: Drop struct board_info

Because the only member of struct board_info is the name, the
board_info[] array of struct board_info elements can be replaced with
an array of strings.

Modify the code accordingly and drop struct board_info.

No intentional functional impact.

Subject: [PATCH 110/135] thermal: intel: powerclamp: Fix cur_state for multi
 package system

The powerclamp cooling device cur_state shows actual idle observed by
package C-state idle counters. But the implementation is not sufficient
for multi package or multi die system. The cur_state value is incorrect.
On these systems, these counters must be read from each package/die and
somehow aggregate them. But there is no good method for aggregation.

It was not a problem when explicit CPU model addition was required to
enable intel powerclamp. In this way certain CPU models could have
been avoided. But with the removal of CPU model check with the
availability of Package C-state counters, the driver is loaded on most
of the recent systems.

For multi package/die systems, just show the actual target idle state,
the system is trying to achieve. In powerclamp this is the user set
state minus one.

Also there is no use of starting a worker thread for polling package
C-state counters and applying any compensation for multiple package
or multiple die systems.

Subject: [PATCH 112/135] powercap: idle_inject: Add update callback

The powercap/idle_inject core uses play_idle_precise() to inject idle
time. But play_idle_precise() can't ensure that the CPU is fully idle
for the specified duration because of wakeups due to interrupts. To
compensate for the reduced idle time due to these wakes, the caller
can adjust requested idle time for the next cycle.

The goal of idle injection is to keep system at some idle percent on
average, so this is fine to overshoot or undershoot instantaneous idle
times.

The idle inject core provides an interface idle_inject_set_duration()
to set idle and runtime duration.

Some architectures provide interface to get actual idle time observed
by the hardware. So, the effective idle percent can be adjusted using
the hardware feedback. For example, Intel CPUs provides package idle
counters, which is currently used by Intel powerclamp driver to
readjust runtime duration.

When the caller's desired idle time over a period is less or greater
than the actual CPU idle time observed by the hardware, caller can
readjust idle and runtime duration for the next cycle.

The only way this can be done currently is by monitoring hardware idle
time from a different software thread and readjust idle and runtime
duration using idle_inject_set_duration().

This can be avoided by adding a callback which callers can register and
readjust from this callback function.

Add a capability to register an optional update() callback, which can be
called from the idle inject core before waking up CPUs for idle injection.
This callback can be registered via a new interface:
idle_inject_register_full().

During this process of constantly adjusting idle and runtime duration
there can be some cases where actual idle time is more than the desired.
In this case idle inject can be skipped for a cycle. If update() callback
returns false, then the idle inject core skips waking up CPUs for the
idle injection.

Subject: [PATCH 113/135] thermal: intel: powerclamp: Use powercap idle-inject
 feature

There are two idle injection implementation in the Linux kernel. One
via intel_powerclamp and the other using powercap/idle_inject. Both
implementation end up in calling play_idle* function from a FIFO
priority thread. Both can't be used at the same time.

It is better to use one idle injection framework for better
maintainability. In this way, there is only one caller for play_idle.

Here powercap/idle_inject can be used for both per-core and for system
wide idle injection. This framework has a well defined interface which
allow registry for per-core or for all CPUs (system wide).

This reduces code complexity in the intel powerclamp driver as all the
per CPU kthreads, delayed work and calls to play_idle can be removed.

The changes include:
 - Remove unneeded include files
 - Remove per CPU kthread workers: balancing_work and idle_injection_work.
 - Reuse the compensation related code by moving from previous worker
   thread to idle_injection callback.
 - Adjust the idle_duration and runtime by using powercap/idle_inject
   interface.
 - Remove all variables, which are not required once powercap/idle_inject
   is used.
 - Add mutex to avoid race during removal of idle injection during module
   unload and user action to change idle inject percent. Also for
   protection during dynamic adjustment of run and idle time from
   update() callback.
 - Remove online/offline callbacks to designate control CPU
 - Use cpu_present_mask global variable for CPU mask
 - Remove hot plug locks

Subject: [PATCH 115/135] thermal: intel: powerclamp: Return last requested
 state as cur_state

When the user is reading cur_state from the thermal cooling device for
Intel powerclamp device:
 - It returns the idle ratio from Package C-state counters when
   there is active idle injection session.
 - -1, when there is no active idle injection session.

This information is not very useful as the package C-state counters vary
a lot from read to read. Instead just return the last requested cur_state.

Subject: [PATCH 116/135] thermal: intel: powerclamp: Fix duration module
 parameter

After the switch to use the powercap/idle-inject framework in the Intel
powerclamp driver, the idle duration unit is microsecond.

However, the module parameter for idle duration is in milliseconds, so
convert it to microseconds in the "set" callback and back to milliseconds
in a new "get" callback.

While here, also use mutex protection for setting and getting "duration".

The other uses of "duration" are already protected by the mutex.

Fixes: 8526eb7fc75a ("thermal: intel: powerclamp: Use powercap idle-inject feature")

Follow the advice in Documentation/filesystems/sysfs.rst that show()
should only use sysfs_emit() or sysfs_emit_at() when formatting the

Subject: [PATCH 119/135] thermal: intel: powerclamp: Add two module parameters

In some use cases, it is desirable to only inject idle on certain set
of CPUs. For example on Alder Lake systems, it is possible that we force
idle only on P-Cores for thermal reasons. Also the idle percent can be
more than 50% if we only choose partial set of CPUs in the system.

Introduce 2 new module parameters for this purpose. They can be only
changed when the cooling device is inactive.

cpumask (Read/Write): A bit mask of CPUs to inject idle. The format of
this bitmask is same as used in other subsystems like in
/proc/irq/*/smp_affinity. The mask is comma separated 32 bit groups.
Each CPU is one bit. For example for 256 CPU system the full mask is:
ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff,ffffffff
The rightmost mask is for CPU 0-32.

max_idle (Read/Write): Maximum injected idle time to the total CPU time
ratio in percent range from 1 to 100. Even if the cooling device max_state
is always 100 (100%), this parameter allows to add a max idle percent
limit. The default is 50, to match the current implementation of powerclamp
driver. Also doesn't allow value more than 75, if the cpumask includes
every CPU present in the system.

Also when the cpumask doesn't include every CPU, there is no use of
compensation using package C-state idle counters. Hence don't start
package C-state polling thread even for a single package or a single die
system in this case.

Subject: [PATCH 124/135] thermal/drivers/mediatek: Relocate driver to mediatek
 folder

Add MediaTek proprietary folder to upstream more thermal zone and cooler
drivers, relocate the original thermal controller driver to it, and rename it
as "auxadc_thermal.c" to show its purpose more clearly.

Subject: [PATCH 126/135] thermal/drivers/mediatek: Add the Low Voltage Thermal
 Sensor driver

The Low Voltage Thermal Sensor (LVTS) is a multiple sensors, multi
controllers contained in a thermal domain.

A thermal domains can be the MCU or the AP.

Each thermal domains contain up to seven controllers, each thermal
controller handle up to four thermal sensors.

The LVTS has two Finite State Machines (FSM), one to handle the
functionin temperatures range like hot or cold temperature and another
one to handle monitoring trip point. The FSM notifies via interrupts
when a trip point is crossed.

The interrupt is managed at the thermal controller level, so when an
interrupt occurs, the driver has to find out which sensor triggered
such an interrupt.

The sampling of the thermal can be filtered or immediate. For the
former, the LVTS measures several points and applies a low pass
filter.

Content-Transfer-Encoding: 8bit

Document support for the Thermal Sensor/Chip Internal Voltage
Monitor/Core Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4H
(R8A779G0) SoC.

Unlike most other R-Car Gen3 and Gen4 SoCs, it has 4 instead of 3
sensors, so increase the maximum number of reg tuples.
Just like other R-Car Gen4 SoCs, interrupts are not routed to the
INTC-AP but to the ECM.

Subject: [PATCH 128/135] thermal/drivers/rcar_gen3: Add support for R-Car V4H
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add support for the Thermal Sensor/Chip Internal Voltage Monitor/Core
Voltage Monitor (THS/CIVM/CVM) on the Renesas R-Car V4H (R8A779G0) SoC.

According to the R-Car V4H Hardware User's Manual Rev. 0.70, the
(preliminary) conversion formula for the thermal sensor is the same as
for most other R-Car Gen3 and Gen4 SoCs, while the (preliminary)
conversion formula for the chip internal voltage monitor differs.
As the driver only uses the former, no further changes are needed.

MIME-Version: 1.0

There is no need to explicitly call set_trips() when resuming from
suspend. The thermal framework calls thermal_zone_device_update() that

 local ops struct
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The callback operations are modified on a driver global level. If one
device tree description do not define interrupts, the set_trips()
operation was disabled globally for all users of the driver.

Fix this by creating a device local copy of the operations structure and
modify the copy depending on what the device can do.

Subject: [PATCH 131/135] thermal/drivers/rcar_gen3_thermal: Fix device
 initialization
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The thermal zone is registered before the device is register and the
thermal coefficients are calculated, providing a window for very
incorrect readings.

The reason why the zone was register before the device was fully
initialized was that the presence of the set_trips() callback is used to
determine if the driver supports interrupt or not, as it is not defined
if the device is incapable of interrupts.

Fix this by using the operations structure in the private data instead
of the zone to determine if interrupts are available or not, and
initialize the device before registering the zone.

Subject: [PATCH 132/135] thermal/drivers/hisi: Drop second sensor hi3660

The commit 74c8e6bffbe1 ("driver core: Add __alloc_size hint to devm
allocators") exposes a panic "BRK handler: Fatal exception" on the
hi3660_thermal_probe funciton.
This is because the function allocates memory for only one
sensors array entry, but tries to fill up a second one.

Fix this by removing the unneeded second access.

Subject: [PATCH 134/135] thermal: Remove core header inclusion from drivers
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As the name states "thermal_core.h" is the header file for the core
components of the thermal framework.

Too many drivers are including it. Hopefully the recent cleanups
helped to self encapsulate the code a bit more and prevented the
drivers to need this header.

Remove this inclusion in every place where it is possible.

Some other drivers did a confusion with the core header and the one
exported in linux/thermal.h. They include the former instead of the
latter. The changes also fix this.

The tegra/soctherm driver still remains as it uses an internal
function which need to be replaced.

The Intel HFI driver uses the netlink internal framework core and
should be changed to prevent to deal with the internals.

No functional changes intended.

Subject: [PATCH 135/135] thermal/drivers/st: Remove syscfg based driver

The syscfg based thermal driver is only supporting STiH415 STiH416 and
STiD127 platforms which are all no more supported.  We can thus safely
remove this driver since the remaining STi platform STiH407/STiH410
and STiH418 are all using the memmap based thermal driver.
