Super-IO accesses may fail on a system with no or unmapped LPC bus.
Also, other drivers may attempt to access the LPC bus at the same time,
resulting in undefined behavior.Use request_muxed_region() to ensure that IO access on the requested
address space is supported, and to ensure that access by multiple drivers
is synchronized.Fixes: b72656dbc491 ("hwmon: (w83627hf) Stop using globals for I/O port numbers")

On suspend some register values are lost, most notably the Value RAM
areas but also other limits. Restore them on resume. On top of that,
some fixups are needed to work around BIOS bugs, in particular when
the BIOS omits running the same initialization sequence on resume
that it does after boot. In that case we have to carry initialization
over suspend.Signed-off-by: Jean Delvare

Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
on old designs were ACPI either wasn't supported or didn't deal with
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.Signed-off-by: Jean Delvare

Drop the reset parameter of the w83627hf driver. It seems it wasn't
that useful. It was dropped from the Linux 2.4 version of this driver
back in July 2004.The only users who have reported that they were still using this
parameter, needed it to switch the chip from automatic fan speed
control back to manual mode. Now that the driver creates pwmN_enable
sysfs files, users will be able to use these files instead, which is
way less agressive.Signed-off-by: Jean Delvare

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.Signed-off-by: Jean Delvare

This hoists nr-1 offset out of (show|store)_temp_*(.*) callbacks, and into
SENSOR_DEVICE_ATTRs for sysfs tempN_X files. It also combines
temp[1] and temp_add[2] (array) fields in w83627hf_data into 3 elem arrays,
which simplifies special-case handling of nr, allowing simplification
of callback bodies and rerolling a flattened loop in
w83627hf_update_device(struct device *dev).The array conversion changes temp[1] from u8 to u16, but this was
happening implicitly via the helper functions anyway.Signed-off-by: Jim Cromie

The bank switching code assumes that the bank selector is set to 0
when the driver is loaded. This might not be the case. This is exactly
the same bug as was fixed in the w83627ehf driver two months ago:
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=0956895aa6f8dc6a33210967252fd7787652537dIn practice, this bug was causing the sensor thermal types to be
improperly reported for my W83627THF the first time I was loading the
w83627hf driver. From the driver history, I'd say that it has been
broken since September 2005 (when we stopped resetting the chip by
default at driver load.)Signed-off-by: Jean Delvare
