The newly introduced Energy Model framework manages power cost tables in
a generic way. Moreover, it supports several types of models since the
tables can come from DT or firmware (through SCMI) for example. On the
other hand, the cpu_cooling subsystem manages its own power cost tables
using only DT data.
In order to avoid the duplication of data in the kernel, and in order to
enable IPA with EMs coming from more than just DT, remove the private
tables from cpu_cooling.c and migrate it to using the centralized EM
framework. Doing so should have no visible functional impact for
existing users of IPA since:
- recent extenstions to the the PM_OPP infrastructure enable the
registration of EMs in PM_EM using the DT property used by IPA;
- the existing upstream cpufreq drivers marked with the
'CPUFREQ_IS_COOLING_DEV' flag all use the aforementioned PM_OPP
infrastructure, which means they all support PM_EM. The only two
exceptions are qoriq-cpufreq which doesn't in fact use an EM and
scmi-cpufreq which doesn't use DT for power costs.
For existing users of cpu_cooling, PM_EM tables will contain the exact
same power values that IPA used to compute on its own until now. The
only new dependency for them is to compile in CONFIG_ENERGY_MODEL.
The case where the thermal subsystem is used without an Energy Model
(cpufreq_cooling_ops) is handled by looking directly at CPUFreq's
frequency table which is already a dependency for cpu_cooling.c anyway.
Since the thermal framework expects the cooling states in a particular
order, bail out whenever the CPUFreq table is unsorted, since that is
fairly uncommon in general, and there are currently no users of
cpu_cooling for this use-case.

Currently a multiply operation is being performed on two int values
and the result is being assigned to a u64, presumably because the
end result is expected to be probably larger than an int. However,
because the multiply is an int multiply one can get overflow. Avoid
the overflow by casting degc to a u64 to force a u64 multiply.
Also use div_u64 for the divide as suggested by Daniel Lezcano.

Amlogic G12A and G12B SoCs integrate two thermal sensors
with the same design. One is located close to the DDR controller
and the other one is located close to the PLLs (between the CPU and GPU).
The calibration data for each of the thermal sensors instance is stored
in a different location within the AO region.
Implement reading the temperature from each thermal sensor.
The IP block has more functionality, which may be added to this driver
in the future:
- chip reset when the temperature exceeds a configurable threshold
- up to four interrupts when the temperature has risen above a
configurable threshold
- up to four interrupts when the temperature has fallen below a
configurable threshold

Depending on the IP version, TSENS supports upper, lower and critical
threshold interrupts. We only add support for upper and lower threshold
interrupts for now.
TSENSv2 has an irq [status|clear|mask] bit tuple for each sensor while
earlier versions only have a single bit per sensor to denote status and
clear. These differences are handled transparently by the interrupt
handler. At each interrupt, we reprogram the new upper and lower threshold
in the .set_trip callback.

There are two fields - id and hw_id - to track what sensor an action was
to performed on. This was because the sensors connected to a TSENS IP
might not be contiguous i.e. 1, 2, 4, 5 with 3 being skipped.
This causes confusion in the code which uses hw_id sometimes and id
other times (tsens_get_temp, tsens_get_trend).
Switch to only using the hw_id field to track the physical ID of the
sensor. When we iterate through all the sensors connected to an IP
block, we use an index i to loop through the list of sensors, and then
return the actual hw_id that is registered on that index.

Replace the CPU device PM QoS used for the management of min and max
frequency constraints in cpufreq (and its users) with per-policy
frequency QoS to avoid problems with cpufreq policies covering
more then one CPU.
Namely, a cpufreq driver is registered with the subsys interface
which calls cpufreq_add_dev() for each CPU, starting from CPU0, so
currently the PM QoS notifiers are added to the first CPU in the
policy (i.e. CPU0 in the majority of cases).
In turn, when the cpufreq driver is unregistered, the subsys interface
doing that calls cpufreq_remove_dev() for each CPU, starting from CPU0,
and the PM QoS notifiers are only removed when cpufreq_remove_dev() is
called for the last CPU in the policy, say CPUx, which as a rule is
not CPU0 if the policy covers more than one CPU. Then, the PM QoS
notifiers cannot be removed, because CPUx does not have them, and
they are still there in the device PM QoS notifiers list of CPU0,
which prevents new PM QoS notifiers from being registered for CPU0
on the next attempt to register the cpufreq driver.
The same issue occurs when the first CPU in the policy goes offline
before unregistering the driver.
After this change it does not matter which CPU is the policy CPU at
the driver registration time and whether or not it is online all the
time, because the frequency QoS is per policy and not per CPU.

This patch rewrites the DB8500 thermal sensor to be a
pure OF sensor, so that it can be used with thermal zones
defined in the device tree.
This driver was initially merged before we had generic
thermal zone device tree bindings, and now it gets
modernized to the way we do things these days.
The old driver depended on a set of trigger points
provided in the device tree or platform data to
interpolate the current temperature between trigger
points depending on whether the trend was rising or
falling. This was bad because the trigger points should
be used for defining temperature zone policies and
bind to cooling devices.
As the PRCMU (power reset control management unit) can
only issue IRQs when we pass temperature trigger points
upward or downward We instead define a number of
temperature points inside the driver ranging from
15 to 100 degrees celsius. The effect is that when
we register the device we quickly trigger 15, 20 ... up
to the room temperature in succession and then we
get continous event IRQs also under normal operating
conditions, and the temperature of the system is now
reported more accurately (+/- 2.5 degrees celsius)
while in the past the first trigger point was at 70
degrees and the average temperature was simply reported
as 35 degrees celsius (between 70 degrees and 0) until
we passed 70 degrees which didn't accurately represent
the temperature of the system.
As a result of dropping all the trigger points from the
driver and reusing the core DT thermal zone management
code we reduce the code footprint quite a bit.

This change exports an interface to read tcc offset and allow writing if
the platform is not locked.
Refer to Intel SDM for details on the MSR: MSR_TEMPERATURE_TARGET.
Here TCC Activation Offset (R/W) bits allow temperature offset in degrees
in relation to TjMAX.
This change will be useful for improving performance from user space for
some platforms, if the current offset is not optimal.

Passing 0 to cpuhp_remove_state() triggers the BUG_ON() in
__cpuhp_remove_state_cpuslocked() and the argument passed to
powercap_unregister_control_type() is expected to be a valid

Here is the "big" driver core and debugfs changes for 5.3-rc1
It's a lot of different patches, all across the tree due to some api
changes and lots of debugfs cleanups. Because of this, there is going
to be some merge issues with your tree at the moment, I'll follow up
with the expected resolutions to make it easier for you.
Other than the debugfs cleanups, in this set of changes we have:
- bus iteration function cleanups (will cause build warnings
with s390 and coresight drivers in your tree)
- scripts/get_abi.pl tool to display and parse Documentation/ABI
entries in a simple way
- cleanups to Documenatation/ABI/ entries to make them parse
easier due to typos and other minor things
- default_attrs use for some ktype users
- driver model documentation file conversions to .rst
- compressed firmware file loading
- deferred probe fixes
All of these have been in linux-next for a while, with a bunch of merge
issues that Stephen has been patient with me for. Other than the merge
issues, functionality is working properly in linux-next :)

cpus=0000000f freq=408000 cdev_state=10 power=416
There seems to be no good reason for omitting the CPU load information
depending on another tracepoint. My guess is that the intention was to
check whether thermal_power_cpu_get_power is (still) enabled, however
'load_cpu != NULL' already indicates that it was at least enabled when
cpufreq_get_requested_power() was entered, there seems little gain
from omitting the assignment if the tracepoint was just disabled, so
just remove the check.

Explicitly use the pinctrl to set/unset the right mode
instead of relying on the pinctrl init mode.
And it requires setting the tshut polarity before select pinctrl.
When the temperature sensor mode is set to 0, it will automatically
reset the board via the Clock-Reset-Unit (CRU) if the over temperature
threshold is reached. However, when the pinctrl initializes, it does a
transition to "otp_out" which may lead the SoC restart all the time.
"otp_out" IO may be connected to the RESET circuit on the hardware.
If the IO is in the wrong state, it will trigger RESET.
(similar to the effect of pressing the RESET button)
which will cause the soc to restart all the time.

Currently IRQF_SHARED type interrupt line is allocated, but it

By changing interrupt type to IRQF_ONESHOT, now irq handler is
no longer needed, as clear of interrupt status can be done in
threaded interrupt context.
Because IRQF_ONESHOT type interrupt line is kept disabled until
the threaded handler has been run, so there is no need to protect

thermal_of_cooling_device_register() and thermal_cooling_device_register()
are typically called from driver probe functions, and
thermal_cooling_device_unregister() is called from remove functions. This
makes both a perfect candidate for device managed functions.
Introduce devm_thermal_of_cooling_device_register(). This function can
also be used to replace thermal_cooling_device_register() by passing a NULL
pointer as device node. The new function requires both struct device *
and struct device_node * as parameters since the struct device_node *
parameter is not always identical to dev->of_node.
Don't introduce a device managed remove function since it is not needed

Just rename the function and move it to allow code sharing with future
versions of TSENS IP

The current implementation is based on an algorithm published in the
docs. Instead of reading the temperature thrice w/o any explanation,
improve the algorithm.
This will become the basis for a common get_temp routine in the future.

The IP can support 'm' sensors while the platform can enable 'n' sensors
of the 'm' where n <= m.
Track maximum sensors supported by the IP so that we can correctly track
what subset of the sensors are supported on the platform.

is_sensor_enabled() checks if the sensors are enabled on this platform.
It is possible that the SoC might choose not to enable all the sensors
that the IP block is capable of supporting.

We print a calibration failure message on -EPROBE_DEFER from
nvmem/qfprom as follows:
[ 3.003090] qcom-tsens 4a9000.thermal-sensor: version: 1.4
[ 3.005376] qcom-tsens 4a9000.thermal-sensor: tsens calibration failed
[ 3.113248] qcom-tsens 4a9000.thermal-sensor: version: 1.4
This confuses people when, in fact, calibration succeeds later when
nvmem/qfprom device is available. Don't print this message on a
-EPROBE_DEFER.

As we add support for newer versions of the TSENS IP, the current
approach isn't scaling because registers and bitfields get moved around,
requiring platform-specific hacks in the code. By moving to regmap, we
can hide the register level differences away from the code.
Define a common set of registers and bit-fields that we care about
across the various tsens IP versions.

8974 and 8916 have the same version of the TSENS IP. Merge the files to
allow for better code reuse.

Some #defines in tsens-v_0_1.c clash with those in tsens-8974.c. Prefix
them with 8916 to avoid the clash so we can merge the two files.

8916 and 8974 use v0.1.0 of the TSENS IP. Rename tsens-8916 to prepare
it for merging with tsens-8974 in a later commit.

tsens_get_temp() uses the name 'data' for the void pointer, use the same
in tsens_get_trend() for consistency.

tmdev seems to imply that this is a device pointer when in fact it is
just private platform data for each tsens device. Rename it to priv
