Pull thermal control updates from Rafael Wysocki:
"These mostly continue to rework the thermal core and the thermal zone
driver interface to make the code more straightforward and reduce
bloat

The most significant piece of this work is a change of the code
related to binding cooling devices to thermal zones which, among other
things, replaces two previously existing thermal zone operations with
one allowing driver implementations to be much simpler

There is also a new thermal core testing module allowing mock thermal
zones to be created and controlled via debugfs in order to exercise
the thermal core functionality. It is expected to be used for
implementing thermal core self tests in the future

Apart from the above, there are assorted thermal driver updates

Specifics:

- Update some thermal drivers to eliminate thermal_zone_get_trip()
calls from them and get rid of that function (Rafael Wysocki)

- Update the thermal sysfs code to store trip point attributes in
trip descriptors and get to trip points via attribute pointers
(Rafael Wysocki)

- Move the computation of the low and high boundaries for
thermal_zone_set_trips() to __thermal_zone_device_update() (Daniel
Lezcano)

- Introduce a debugfs-based facility for thermal core testing (Rafael
Wysocki)

- Replace the thermal zone .bind() and .unbind() callbacks for
binding cooling devices to thermal zones with one .should_bind()
callback used for deciding whether or not a given cooling devices
should be bound to a given trip point in a given thermal zone
(Rafael Wysocki)

- Eliminate code that has no more users after the other changes, drop
some redundant checks from the thermal core and clean it up (Rafael
Wysocki)

- Fix rounding of delay jiffies in the thermal core (Rafael Wysocki)

- Refuse to accept trip point temperature or hysteresis that would
lead to an invalid threshold value when setting them via sysfs
(Rafael Wysocki)

- Adjust states of all uninitialized instances in the .manage()
callback of the Bang-bang thermal governor (Rafael Wysocki)

- Drop a couple of redundant checks along with the code depending on
them from the thermal core (Rafael Wysocki)

- Rearrange the thermal core to avoid redundant checks and simplify
control flow in a couple of code paths (Rafael Wysocki)

- Add power domain DT bindings for new Amlogic SoCs (Georges Stark)

- Switch from CONFIG_PM_SLEEP guards to pm_sleep_ptr() in the ST
driver and add a Kconfig dependency on THERMAL_OF subsystem for the
STi driver (Raphael Gallais-Pou)

- Simplify the error code path in the probe functions in the brcmstb
driver with the helo of dev_err_probe() (Yan Zhen)

- Make imx_sc_thermal use dev_err_probe() (Alexander Stein)

- Remove trailing space after \n newline in the Renesas driver (Colin
Ian King)

- Add DT binding compatible string for the SA8255p to the tsens
thermal driver (Nikunj Kela)

- Use the devm_clk_get_enabled() helpers to simplify the init routine
in the sprd thermal driver (Huan Yang)

- Remove __maybe_unused notations for the functions by using the new
RUNTIME_PM_OPS() and SYSTEM_SLEEP_PM_OPS() macros on the IMx and
Qoriq drivers (Fabio Estevam)

- Remove unused declarations from the ti-soc-thermal driver's header
file as the functions in question were removed previously (Zhang
Zekun)"

thermal: stm: Convert to platform remove callback returning void

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

"These rework the Intel DTS IOSF and the ACPI thermal drivers to pass

This includes changes that are present in the ACPI updates too,

Specifics:

remove thermal zone callbacks that are not necessary any more from
that driver (Rafael Wysocki)

- Fix a few issues in the Intel DTS IOSF thermal driver, clean up
code in it and make it pass tables of generic trip point structures
to the core during thermal zone registration (Rafael Wysocki)

- Drop a redundant check from the Intel DTS IOSF thermal driver's
"remove" routine (Zhang Rui)

- Use module_platform_driver() to replace an open-coded counterpart
of it in the int340x thermal driver (Yang Yingliang)

- Fix possible uninitialized value access in __thermal_of_bind() and
__thermal_of_unbind() (Peng Fan)

- Make the int3400 driver use thermal zone device wrappers (Daniel

- Remove redundant thermal zone state check from the int340x thermal
driver (Daniel Lezcano)

- Drop non-functional nocrt parameter from ACPI thermal (Mario
Limonciello)

- Explicitly include correct DT includes in the thermal core and
drivers (Rob Herring)"
