1d4d673359 hwmon: (npcm750-pwm-fan) Remove another unused field in struct npcm7xx_cooling_device
In "struct npcm7xx_cooling_device", the 'pwm_clk_freq' field is only
written and never used.

Remove it and update npcm7xx_pwm_init() accordingly.

d8a66f3621 hwmon: Drop explicit initialization of struct i2c_device_id::driver_data to 0
These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.

This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

801fec8df5 hwmon: (max31790) revise the scale to write pwm
Since the value for PWMOUT Target Duty Cycle register is a 9 bit
left-justified value that ranges from 0 to 511 and is contained in 2
bytes.

There is an issue that the PWM signal recorded by oscilloscope would
not be on consistently if we set PWM to 100% to the driver.

It is because the LSB of the 9 bit would always be zero if it just
left shift 8 bit for the value that write to PWMOUT Target Duty
Cycle register.

Therefore, revise the scale of the value that was written to pwm input
from 255 to 511 and modify the value to left-justified value.

e58095cfc5 hwmon: (it87) Test for chipset before entering configuration mode
Major part of the change for the new method to avoid chipset issues.

The actual update does the following:

1) Lock the memory, but does not perform a SIO entry (previously it
would have performed an SIO entry).

2) Attempt to read the chipID.  This should be safe no matter which
chip we have.

3) If step (2) fails, then perform SIO entry and retry chipID read.  For
older chips and on failure it acts similarly to prior to this patch.

4) Set the sio_data->type, similar to previously.

5) If we have not performed an SIO entry, and this is not a chip type
with the NOCONF feature, then it will perform an SIO entry at this
point.

6) Proceed with setup as prior to this patch.

7) Any following access to the SIO registers will invoke the SIO entry
and SIO exit steps unless it is a chip with the NOCONF feature set.
This was set up in the previous patches in this patchset.

8) Update to the exit based on if it had performed a SIO entry or not.

f0c344c000 hwmon: (coretemp) Extend the bitmask to read temperature to 0xff
The Intel Software Development manual defines the temperature digital
readout as the bits [22:16] of the IA32_[PACKAGE]_THERM_STATUS registers.
Bit 23 is specified as reserved.

In recent processors, however, the temperature digital readout uses bits
[23:16]. In those processors, using the bitmask 0x7f would lead to
incorrect readings if the temperature deviates from TjMax by more than
127 degrees Celsius.

Although not guaranteed, bit 23 is likely to be 0 in processors from a few
generations ago. The temperature reading would still be correct in those
processors when using a 0xff bitmask.

Model-specific provisions can be made for older processors in which bit 23
is not 0 should the need arise.

e27cbb607f hwmon: (aspeed-g6-pwm-tach) 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() is renamed to .remove().

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

71113b9be4 hwmon: (acpi_power_meter) Ensure IPMI space handler is ready on Dell systems
The following error can be observed at boot:
[    3.717920] ACPI Error: No handler for Region [SYSI] (00000000ab9e62c5) [IPMI] (20230628/evregion-130)

[    3.717957] ACPI: \_SB_.PMI0: _PMC evaluation failed: AE_NOT_EXIST

On Dell systems several methods of acpi_power_meter access variables in
IPMI region [0], so wait until IPMI space handler is installed by
acpi_ipmi and also wait until SMI is selected to make the space handler
fully functional.

Since the dependency is inside BIOS's ASL code and it's not
discoverable, so use this fixup is a hack to workaround BIOS issue.

670e98a34a ACPI: IPMI: Add helper to wait for when SMI is selected
On Dell servers, many APCI methods of acpi_power_meter module evaluate
variables inside IPMI region, so the region handler needs to be
installed. In addition to that, the handler needs to be fully
functional, and that depends on SMI being selected.

So add a helper to let acpi_power_meter know when the handler is
installed and ready to be used.

Update links in the documentation and in-code comments which point to

The current links don't work because National Semiconductor (which is the
original manufacturer of this chip) has been a part of Texas Instruments
since 2011 and http://www.national.com/ doesn't work anymore.

c7506a2b5a hwmon: (pmbus/mp2975) Fix IRQ masking
The MP2971/MP2973 use a custom 16bit register format for
SMBALERT_MASK which doesn't follow the PMBUS specification.

Map the PMBUS defined bits used by the common code onto the custom
format used by MPS and since the SMBALERT_MASK is currently never read
by common code only implement the mapping for write transactions.
