Guenter Roeck 585c0fd821 hwmon: (w83627ehf) Fix number of fans for NCT6776F
NCT6776F can select fan input pins for fans 3 to 5 with a secondary set of
chip register bits. Check that second set of bits in addition to the first set
to detect if fans 3..5 are monitored.

Guenter Roeck bfa02b0da6 hwmon: (w83627ehf) Fix broken driver init
Commit 2265cef2 (hwmon: (w83627ehf) Properly report PECI and AMD-SI
sensor types) results in kernel panic if data->temp_label was not
initialized.
The problem was found with chip W83627DHG-P.

Add check if data->temp->label was set before use.

Based on incomplete patch by Alexander Beregalov.

Jean Delvare eff7687d47 hwmon: (w83627ehf) Add support for the W83627UHG
This is essentially a stripped down version of the W83627DHG. Noticeable
difference is that it is still powered with +5V, as older models, even
though the ADC resolution is 8 mV as newer models have.

The probe function has grown pretty large, I think it's time for some

Jean Delvare bf164c58e5 hwmon: (w83627ehf) Properly report thermal diode sensors
The w83627ehf driver is improperly reporting thermal diode sensors as
type 2, instead of 3. This caused "sensors" and possibly other
monitoring tools to report these sensors as "transistor" instead of
"thermal diode".

Furthermore, diode subtype selection (CPU vs. external) is only
supported by the original W83627EHF/EHG. All later models only support
CPU diode type, and some (NCT6776F) don't even have the register in
question so we should avoid reading from it.

need to correct it if the fan divisor value is changed, and the above

Guenter Roeck 26bc440e3f hwmon: (w83627ehf) Use 16 bit fan count registers if supported
Some of the chips supported by this driver have 13 bit or 16 bit fan count
registers. This patch improves support for those registers, specifically for
NCT6775F. With the changes in this patch, fan speed is reported correctly even
if the fan divider is set to a low value, which results in a fan speed reading
above 0xff.

With this patch, the width of fan count registers is no longer used to determine
if the chip has fan divider register(s) or not. A dedicated flag is used instead
to determine if this is the case.

Jean Delvare 67b671bceb hwmon: Let the user override the detected Super-I/O device ID
While it is possible to force SMBus-based hardware monitoring chip
drivers to drive a not officially supported device, we do not have this
possibility for Super-I/O-based drivers. That's unfortunate because
sometimes newer chips are fully compatible and just forcing the driver
to load would work. Instead of that we have to tell the users to
recompile the kernel driver, which isn't an easy task for everyone.

So, I propose that we add a module parameter to all Super-I/O based
hardware monitoring drivers, letting advanced users force the driver
to load on their machine. The user has to provide the device ID of a
supposedly compatible device. This requires looking at the source code or
a datasheet, so I am confident that users can't randomly force a driver
without knowing what they are doing. Thus this should be relatively safe.

As you can see from the code, the implementation is pretty simple and
unintrusive.

and leave with the bank set to something different, so assuming that
the bank value is 0 is not safe.

Mark M. Hoffman ea7be66c44 hwmon: (w83627ehf) read fan_div values during probe
This patch forces the driver to read the fan divider values during early init.
Otherwise, a call to store_fan_min() could access uninitialized variables.

Jean Delvare 7cb7273f8c hwmon/w83627ehf: No need to initialize fan_min
We don't need to initialize fan_min in this driver, as the fan_div
attributes are read-only.

Jean Delvare da667365be hwmon/w83627ehf: Export the thermal sensor types
Add support for the w83627ehf thermal sensor types. I made them read-only,
as the BIOS is supposed to set them up properly. This information makes it
easier to find out which temperature channel corresponds to the CPU.
