Hi Linus,
Please, pull the following patches that fix many fall-through warnings
when building with Clang 12.0.0 and this[1] change reverted. Notice
that in order to enable -Wimplicit-fallthrough for Clang, such change[1]
is meant to be reverted at some point. So, these patches help to move
in that direction.
Thanks!

Support set_trips() callback of thermal device ops. This allows HWMON
device to operatively notify thermal core about temperature changes, which
is very handy to have in a case where HWMON sensor is used by CPU thermal
zone that performs passive cooling and emergency shutdown on overheat.
Thermal core will be able to react faster to temperature changes.
The set_trips() callback is entirely optional. If HWMON sensor doesn't
support setting thermal trips, then the callback is a NO-OP. The dummy
callback has no effect on the thermal core. The temperature trips are
either complement the temperature polling mechanism of thermal core or
replace the polling if sensor can set the trips and polling is disabled
by a particular device in a device-tree.

The min/max/crit and all other temperature values that are passed to
the driver are unlimited and value that is close to INT_MIN results in
integer underflow of the temperature calculations made by the driver
for LM99 sensor. Temperature hysteresis is among those values that need
to be limited, but limiting of hysteresis is independent from the sensor

As per current logic the wait time per conversion is arouns 430ms
for 512 samples and around 860ms for 1024 samples for 3 channels
considering 140us as the bus voltage and shunt voltage sampling
conversion time.
This waiting time is a lot for the continuous mode and even for
the single shot mode. For continuous mode when moving average is
considered the waiting for CVRF bit is not required and the data
from the previous conversion is sufficuent. As mentioned in the
datasheet the conversion ready bit is provided to help coordinate
single-shot conversions, we can restrict the use to single-shot
mode only.
Also, the conversion time is for the averaged samples, the wait
time for the polling can omit the number of samples consideration.

If a fan is not running or not connected, of if fan monitoring is disabled,
the fan count register returns a fixed value of 0xffe0. So far this is then
translated to a RPM value larger than 0. Since this is misleading and does
not really make much sense, report a fan RPM of 0 in this situation.

Fault bits in MAX31790 are sticky and have to be cleared explicitly.
A write operation into either the 'Target Duty Cycle' register or the
'Target Count' register is necessary to clear a fault.
At the same time, we can never clear cached fault status values before
reading them because the companion fault status for any given fan is
cleared as well when clearing a fault.

pwmX_enable supports three possible values:
0: Fan control disabled. Duty cycle is fixed to 0%
1: Fan control enabled, pwm mode. Duty cycle is determined by
values written into Target Duty Cycle registers.
2: Fan control enabled, rpm mode
Duty cycle is adjusted such that fan speed matches
the values in Target Count registers
The current code does not do this; instead, it mixes pwm control
configuration with fan speed monitoring configuration. Worse, it
reports that pwm control would be disabled (pwmX_enable==0) when
it is in fact enabled in pwm mode. Part of the problem may be that
the chip sets the "TACH input enable" bit on its own whenever the
mode bit is set to RPM mode, but that doesn't mean that "TACH input
enable" accurately reflects the pwm mode.
Fix it up and only handle pwm control with the pwmX_enable attributes.
In the documentation, clarify that disabling pwm control (pwmX_enable=0)
sets the pwm duty cycle to 0%. In the code, explain why TACH_INPUT_EN
is set together with RPM_MODE.
While at it, only update the configuration register if the configuration
has changed, and only update the cached configuration if updating the
chip configuration was successful.

The MAX31790 has two sets of registers for pwm duty cycles, one to request
a duty cycle and one to read the actual current duty cycle. Both do not
have to be the same.
When reporting the pwm duty cycle to the user, the actual pwm duty cycle
from pwm duty cycle registers needs to be reported. When setting it, the
pwm target duty cycle needs to be written. Since we don't know the actual
pwm duty cycle after a target pwm duty cycle has been written, set the
valid flag to false to indicate that actual pwm duty cycle should be read
from the chip instead of using cached values.

Fans 7..12 do not have their own set of configuration registers.
So far the code ignored that and read beyond the end of the configuration
register range to get the tachometer period. This resulted in more or less
random fan speed values for those fans.
The datasheet is quite vague when it comes to defining the tachometer
period for fans 7..12. Experiments confirm that the period is the same
for both fans associated with a given set of configuration registers.

The BPA-RS600 doesn't follow the PMBus spec for linear data.
Specifically it treats the mantissa as an unsigned 11-bit value instead
of a two's complement 11-bit value. At this point it's unclear whether
this only affects Vin or if Pin/Pout1 are affected as well. Erring on
the side of caution only Vin is dealt with here.

Current shunt LSB values got reversed during in the
original driver commit.
So, correct the current shunt LSB values according to
the datasheet.
This caused reading slightly skewed current values.

TPS23861 has a configuration bit for setting of the
current shunt value used on the board.
Its bit 0 of the General Mask 1 register.
According to the datasheet bit values are:
0 for 255 mOhm (Default)
1 for 250 mOhm
So, configure the bit before registering the hwmon
device according to the value passed in the DTS or
default one if none is passed.
This caused potentially reading slightly skewed values
due to max current value being 1.02A when 250mOhm shunt
is used instead of 1.0A when 255mOhm is used.

Define the max register address the device supports.
This allows reading the whole register space via
regmap debugfs, without it only register 0x0 is visible.
This was forgotten in the original driver commit.

The scpi hwmon shows the sub-zero temperature in an unsigned integer,
which would confuse the users when the machine works in low temperature
environment. This shows the sub-zero temperature in an signed value and
users can get it properly from sensors.
