Add regulator supply into PWBUS_REGULATOR macro. This makes it optional
to define a vin-supply in DT. Not defining a supply will add a dummy
regulator supply instead and only cause the following debug output:
```

On the Dell Inspiron 3505, three temperature sensors are
available through the SMM interface. However since they
do not have an associated type, they are not detected.
Probe for those sensors in case no type was detected.
_i8k_get_temp() is used instead of i8k_get_temp()
since it is sometimes faster and the result is
easier to check (no -ENODATA) since we do not
care about the actual temp value.

Right now, we only use bits 0 to 7 of the fan/temp sensor number
by doing number & 0xff. Passing the value as a u8 makes this
step unnecessary. Also add checks to the ioctl handler since
users might get confused when passing 0x00000101 does the same
as passing 0x00000001.

When enabling said module parameter, the driver ignores
all feature blacklists on relevant models, which has the
potential for strange side effects. Also there seems to
be a slight chance for unsupported devices to behave
badly when probed for features.
In such cases, the kernel should be tainted to inform
people that these issues might have been caused by
the dell_smm_hwmon driver with "force" enabled.
Also reword the parameter description to remind users
that enabling "force" also enables blacklisted features.

Reading DSDT code for ASUS X470-based boards (the ones served by the
asus_wmi_Sensors driver), where ASUS put hardware monitoring functions
into the WMI code, reveals that fan and current sensors data is
unsigned. For the current sensor that was confirmed by a user who showed
high enough current value for overflow.
Thus let's assume that the signedness of the sensors is determined by its
type and that only temperature ones provide signed numbers.

It is not the laptops, but the /proc/i8k interface that is legacy (or so
I think was the intention of the help text author). The old description
was confusing, fix this.
The phrase "Say Y if you intend to run this kernel on old Dell laptops
or want to use userspace package i8kutils." was introduced in 2015, in
commit 039ae58503f3 ("hwmon: Allow to compile dell-smm-hwmon driver without /proc/i8k")
I think that "old laptops" was about hotkey and Fn key support - this
driver in the 2.4 kernels' era apparently had these capabilities
(see: https://github.com/vitorafsr/i8kutils , description of
"repeat_rate" kernel module parameter).

In Kconfig, inside the "Processor type and features" menu, there is
the CONFIG_I8K option: "Dell i8k legacy laptop support". This is
very confusing - enabling CONFIG_I8K is not required for the kernel to
support old Dell laptops. This option is specific to the dell-smm-hwmon
driver, which mostly exports some hardware monitoring information and
allows the user to change fan speed.
This option is misplaced, so move CONFIG_I8K to drivers/hwmon/Kconfig,
where it belongs.
Also, modify the dependency order - change
select SENSORS_DELL_SMM
to
depends on SENSORS_DELL_SMM
as it is just a configuration option of dell-smm-hwmon. This includes
changing the option type from tristate to bool. It was tristate because
it could select CONFIG_SENSORS_DELL_SMM=m .
When running "make oldconfig" on configurations with
CONFIG_SENSORS_DELL_SMM enabled , this change will result in an
additional question (which could be printed several times during
bisecting). I think that tidying up the configuration is worth it,
though.
Next patch tweaks the description of CONFIG_I8K.

Temperature sensor readings are signed, which is hinted by their blank
value (oxd8, 216 as unsigned and -40 as signed). T_Sensor, Crosshair
VIII Hero, and a freezer were used to confirm that.
Here we read fan sensors as signed too, because with their typical
values and 2-byte width, I can't tell a difference between signed and
unsigned, as I don't have a high speed chipset fan.

Recently 'cur_state' user space 'sysfs' interface 'sysfs' has been
deprecated. This interface is used in Nvidia systems for setting fan
speed limit. Currently fan speed limit is set from the user space by
setting 'sysfs' 'cur_state' attribute to 'max_state + n', where 'n' is
required limit, for example: 15 for 50% speed limit, 20 for full fan
speed enforcement.
The purpose of this feature is to provides ability to limit fan speed
according to some system wise considerations, like absence of some
replaceable units (PSU or line cards), high system ambient temperature,
unreliable transceivers temperature sensing or some other factors which
indirectly impacts system's airflow.
The motivation is to support fan low limit feature through 'hwmon'
interface.
Use 'hwmon' 'pwm' attribute for setting low limit for fan speed in
case 'thermal' subsystem is configured in kernel. In this case setting
fan speed through 'hwmon' will never let the 'thermal' subsystem to
select a lower duty cycle than the duty cycle selected with the 'pwm'
attribute.
From other side, fan speed is to be updated in hardware through 'pwm'
only in case the requested fan speed is above last speed set by
'thermal' subsystem, otherwise requested fan speed will be just stored
with no PWM update.

This driver provides the same data as the asus_wmi_ec_sensors driver
(and gets it from the same source) but does not use WMI, polling
the ACPI EC directly.
That provides two enhancements: sensor reading became quicker (on some
systems or kernel configuration it took almost a full second to read
all the sensors, that transfers less than 15 bytes of data), the driver
became more flexible. The driver now relies on ACPI mutex to lock access
to the EC in the same way as the WMI code does.

This patch enables the sch56xx-common module to get automatically
loaded on supported machines.
If a machine supports Fujitsu's SCH56XX-based hardware monitoring
solutions, it contains a "Antiope"/" Antiope" dmi onboard device
in case of the sch5627 or a "Theseus"/" Theseus" dmi onboard device
in case of the sch5636.
Since some machines like the Esprimo C700 have a seemingly faulty
DMI table containing both onboard devices, the driver still needs
to probe for the individual superio chip, which in presence of at
least one DMI onboard device however can be considered safe.
Also add a module parameter allowing for bypassing the
DMI check.

The motivation is to reduce code and to allow easy support for similar
devices by the same driver.

ASUS ROG STRIX B450-F GAMING II has support of the same WMI
monitoring method as ASUS ROG STRIX B450-F GAMING.
This commit adds "ASUS ROG STRIX B450-F GAMING II" to
the list of boards that can be monitored using ASUS WMI.

Asus PRIME B550-PLUS motherboards have got an nct6775 chip. Its resource
range is covered by the \AMW0.SHWM OpRegion, so the chip is unusable
when using SIO. However ASUS WMI access works.
Add PRIME B550-PLUS to the list of motherboards using ASUS WMI to read
data.

ASUS Pro B550M-C/PRIME B550M-A boards have got an nct6775 chip, but
by default there's no use of it because of resource conflict with WMI
method.
This commit adds "Pro B550M-C" and "PRIME B550M-A" to
the list of boards that can be monitored using ASUS WMI.

If a label is defined in the device tree for this device add that
to the device specific attributes. This is useful for userspace to
be able to identify an individual device when multiple identical
chips are present in the system.

These registers report CPU temperatures (and, depending on the system,
sometimes chipset temperatures) via the TSI interface on AMD systems.
They're distinct from most of the other Super-IO temperature readings
(CPUTIN, SYSTIN, etc.) in that they're not a selectable source for
monitoring and are in a different (higher resolution) format, but can
still provide useful temperature data.

According to the March 2013 revision of the LM82 datasheet, the latest
LM82 die revision is 0x03. This was confirmed and observed with a real
chip. Further details in this revision of the LM82 datasheet suggest that
LM82 is now just a repackaged LM83. Such versions of LM82 will be detected
as LM83. Add comment to the code explaining why this may happen.
