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

The RPM after conversion from / before conversion to a register value can be
much more than 65535 (up to 1500000), so putting this into an u16 can cause
overflows. This changes the functions to use an int to store / get RPM instead.Signed-off-by: Hans de Goede

For some reason the fan_attr array for the f71862fg was missing the attr for
the 3th pwm output. This patch fixes this.Signed-off-by: Hans de Goede

Remove the fan_mode module option it was a monstrosity to begin with, and

While studying the datasheets for adding F8000 support, I noticed that the
F718x2 has separate alarms (and beep control) for its max and crit limits.We keep the temp#_alarm attributes as they are, even though it would be more
logical to rename them to temp#_max_alarm. Because lm_sensors v2 depends
on them.Signed-off-by: Hans de Goede

More F8000 prep work. Take over the checking if the hwmon part is not
powered down from the standalone f8000 driver.This check is valid for all supported models.

Simplify fan and temp hyst. handling by treating the registers as an array of
nibbles instead of using switch cases. Also unify the way hysts are handled
between temp and fans, the temp code was storing the actual per temp hyst
values in 4 u8's, where as the fan code was storing actual register values.Signed-off-by: Hans de Goede

While working on adding F8000 support I noticed that various of the
store sysfs functions (and a few of the show also) had issues.This patch fixes the following issues in these functions:
* store: storing the result of strto[u]l in an int, resulting in a possible
overflow before boundary checking
* store: use of f71882fg_update_device(), we don't want to read the whole
device in store functions, just the registers we need
* store: use of cached register values instead of reading the needed regs
in the store function, including cases where f71882fg_update_device() was
not used, this could cause real isues
* show: shown value is a calculation of 2 or more cached register reads,
without locking the data struct.Signed-off-by: Hans de Goede

This patch is a preparation patch for adding F8000 support to the f71882fg
driver. If you look at the register addresses and esp, the bits used for
the temperature channels, then you will notice that it appears that they
start at 1 in a system meant to start at 0. As the F8000 actually uses the 0
addresses and bits, this patch changes the f71882fg driver to take 4
temperatures numbered 0-3 in to account, using 1-3 in this new scheme for
the temperatures actually present in the F718x2FG.Signed-off-by: Hans de Goede

The f71882fg driver did some io to ioports it hadn't reserved yet in its
find (detect) function, this patches moves this io to the probe function
where these ports are reserved and this io belongs.Signed-off-by: Hans de Goede

Add PWM (fan speed control) support to the f71882fg driver. Both
manual control and automatic (temperature-based) modes are supported.
Additionally, each mode has a PWM-based and an RPM-based variant. By
default we use the mode set by the BIOS.Signed-off-by: Hans de Goede

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 is the second version of a new driver for the hardware monitoring features
of the Fintek F71882FG and F71883FG Super-I/O chips. This version has several
small fixes for flaws discovered during the review of the first version.This version of the driver does not support the pwm part of these chips (yet).
I'll first design a sysfs api for this and post that for discussion, and then
implement pwm support as an incremental patch over this one.This driver supports all sensors of this chip, except for the vid inputs. The
vid inputs are somewhat documented in the datasheet, but I know nothing about
vid/vrm stuff. Help with this would be much appreciated.Signed-off-by: Hans de Goede
