Arnd Bergmann d5553c2619 hwmon: (aspeed-pwm) add THERMAL dependency
With CONFIG_THERMAL=m, a built-in aspeed pwm tacho driver causes
a link error:

drivers/hwmon/aspeed-pwm-tacho.o: In function `aspeed_pwm_tacho_probe':
aspeed-pwm-tacho.c:(.text+0x7f0): undefined reference to `thermal_of_cooling_device_register'

This adds a dependency similar to what other hwmon drivers use,
ensuring that the aspeed driver cannot be built-in in this
case but has to be a module. With THERMAL=n, we still allow building it.

Patrick Venture ece0c03a9e hwmon: (aspeed-pwm-tacho) reduce fan_tach period
Reduce the fan_tach period such that the fan controller uses a shorter
period to measure the rpm.

The original period of 0x1000 was chosen as a conversative value from the
reference implementation.  Through experimentation on the quanta-q71l
board, I was able to drive the number down which ultimately reduced the
time the controller would use to determine the fan_tach.  This value was
recently tested and accepted downstream on the IBM Zaius board which uses
the ast2500.

Future work: It may be worthwhile as this is a tunable parameter to the
system, to allow overriding it through the device tree.

Testing: Tested on an ast2400 sitting on a quanta-q71l and ast2500 on
power9.

Carlo Caione ccc9b8263d hwmon: (scpi) Fix the scale of SCP sensor readings
The implementation details for SCPI seems to suggest that the sensor
readings must be reported by SCP using a well defined scale
(millidegree Celsius for temperature, millivolts for voltage,
milliamperes for current, microwatts for power and microjoules for
energy).

This is also important for the interaction with other subsystems: for
example both the thermal sub-system and the hwmon sysfs interface expect
the temperature expressed in millidegree Celsius.

Unfortunately since this behaviour is dependent on the firmware
implementation there are cases where the sensor readings are reported
using a different scale. For example in the Amlogic SoCs the
temperature is reported in degree and not millidegree Celsius.

To take into account this discrepancy and fixup the values reported by
SCP a new compatible 'amlogic,meson-gxbb-scpi-sensors' is introduced and
used in this patch by the scpi-hwmon driver to convert the sensor
readings to the expected scale.

Patrick Venture 1e276292bf hwmon: (aspeed-pwm-tacho) Enable both edge measurement.
The aspeed-pwm-tacho controller supports measuring the fan tach by using
leading, falling, or both edges.  This change allows the driver to
support either of the three configurations and will appropriately modify
the returned tach data.

If the controller is measuring with both edges it can return a value more
quickly to the requestor.  This version of the driver should still take ~1s
to return with an RPM value per fan, however, it can be tuned faster with
double edge counting enabled than without.

I tested this and found the number returned matched what I expected.

Chris Packham 1d58f5efbf hwmon: (adt7475) fan stall prevention
By default adt7475 will stop the fans (pwm duty cycle 0%) when the
temperature drops past Tmin - hysteresis. Some systems want to keep the
fans moving even when the temperature drops so add new sysfs attributes
that configure the enhanced acoustics min 1-3 which allows the fans to
run at the minimum configure pwm duty cycle.

Thomas Gleixner 90b4f30b6d hwmon: (coretemp) Handle frozen hotplug state correctly
The recent conversion to the hotplug state machine missed that the original
hotplug notifiers did not execute in the frozen state, which is used on
suspend on resume.

This does not matter on single socket machines, but on multi socket systems
this breaks when the device for a non-boot socket is removed when the last
CPU of that socket is brought offline. The device removal locks up the
machine hard w/o any debug output.

Prevent executing the hotplug callbacks when cpuhp_tasks_frozen is true.

Thanks to Tommi for providing debug information patiently while I failed to
spot the obvious.

In IT8620E, after setting pwm control to manual, it was observed that
pwm values for fan 4..6 have reversed results (writing 0 results in fans
running at full speed, writing 255 results in fans turned off).

With the new PWM control, pwm polarity for pwm control 4..6 is specified
in its pwm control registers. Those registers are overwritten when setting
the pwm mode or the temperature mapping. Do not touch bit 2..6 of pwm
control registers on register writes to fix the problem.

Guenter Roeck 74d3b64197 hwmon: Relax name attribute validation for new APIs
While invalid name attributes are really not desirable and do mess up
libsensors, enforcing valid names has the detrimental effect of driving
users away from using the new hardware monitoring API, especially those
registering name attributes violating the ABI restrictions. Another
undesirable side effect is that this violation and the resulting error
may only be discovered some time after a conversion to the new API,
which in turn may trigger a revert of that conversion.

To solve the problem, relax validation and only issue a warning instead
of returning an error if a name attribute violating the ABI is provided.
This lets callers continue to provide invalid name attributes while
notifying them about it.

Many thanks are due to Dmitry Torokhov for the idea.
