Srinivas Pandruvada 966d0ab673 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.

Srinivas Pandruvada 6210849654 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.

Srinivas Pandruvada 8526eb7fc7 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

Srinivas Pandruvada 8e47363588 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.

Rafael J. Wysocki b1bf9dbffc 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.

Rafael J. Wysocki 97efecfdbf 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.

Srinivas Pandruvada 5c36cf2784 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.

Rafael J. Wysocki 9e0a9be24b 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.

Daniel Lezcano 5b8de18ee9 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.

Srinivas Pandruvada 6757a7abe4 thermal: intel: int340x: Protect trip temperature from concurrent updates
Trip temperatures are read using ACPI methods and stored in the memory
during zone initializtion and when the firmware sends a notification for
change. This trip temperature is returned when the thermal core calls via
callback get_trip_temp().

But it is possible that while updating the memory copy of the trips when
the firmware sends a notification for change, thermal core is reading the
trip temperature via the callback get_trip_temp(). This may return invalid
trip temperature.

To address this add a mutex to protect the invalid temperature reads in
the callback get_trip_temp() and int340x_thermal_read_trips().

Dmitry Baryshkov 903238a33c 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.

vendor kernels, msm8976 should use standard slope values (3200), while
msm8956 really uses the slope values found in the driver.

overrides to the corresponding init function and use the standard

Daniel Lezcano 2e38a2a981 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.

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.

Daniel Lezcano 7c3d5c20dc 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.

Bryan Brattlof 366444ebe7 thermal/drivers/k3_j72xx_bandgap: Map fuse_base only for erratum workaround
Some of TI's J721E SoCs require a software trimming procedure for the
temperature monitors to function properly. To determine if a particular
J721E is not affected by this erratum, both bits in the WKUP_SPARE_FUSE0
region must be set. Other SoCs, not affected by this erratum, will not
need this region.

Map the 'fuse_base' region only when the erratum fix is needed.

Christian Marangi 89992d95ed thermal/drivers/qcom/tsens: Rework debugfs file structure
The current tsens debugfs structure is composed by:
- a tsens dir in debugfs with a version file
- a directory for each tsens istance with sensors file to dump all the
  sensors value.

This works on the assumption that we have the same version for each
istance but this assumption seems fragile and with more than one tsens
istance results in the version file not tracking each of them.

A better approach is to just create a subdirectory for each tsens
istance and put there version and sensors debugfs file.

Using this new implementation results in less code since debugfs entry
are created only on successful tsens probe.
