f99318b254 hwmon: (adt7475) Implement pwm_use_point2_pwm_at_crit
Implement the non-standard pwm_use_point2_pwm_at_crit sysfs attribute
as the adt7473 driver did.

b180d05084 hwmon: (adt7475) Add support for the ADT7473
Add support for the ADT7473 to the adt7475 driver, and mark the
adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost
the same chip and essentially compatible, so there's no point in
having separate drivers for them.

7669896f49 hwmon: (f71882fg) Add support for the f71889fg (version 2)
This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.

Note that this bit of the patch:
-	val = SENSORS_LIMIT(val, 0, 255);
+
+	if (data->type == f71889fg)
+		val = SENSORS_LIMIT(val, -128, 127);
+	else
+		val = SENSORS_LIMIT(val, 0, 127);

Changes behaviour for already supported models, the new behaviour is correct
as the already supported models have bit 7 of the involved registers fixed at
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.

fc16c56e69 hwmon: (f71882fg) Fix sysfs file removal
There is a bug in the old sysfs file removal, as it uses fxxxx_in_temp_attr
to remove the in and temp sysfs attributes, but fxxxx_in_temp_attr has
temp#_alarm, where as f71858fg_in_temp_attr has temp#_max_alarm, so
the temp#_max_alarm attributes for the f71858fg never get removed.

This patch fixes this by doing the sysfs removal exactly the same way as
the creation instead of being (too) clever, this will also avoid similar
bugs in the future.

b69b039922 hwmon: (f71882fg) Cleanup sysfs attr creation 2/2
This patch merges the f71882fg_auto_pwm_attr array into the
fxxxx_fan_attr resp. fxxxx_auto_pwm_attr array, as the f71882fg_auto_pwm_attr
array was merely extending these 2 with entries for a 4th fan, it also makes
these 2 arrays 2 dimensional so that the rest of the code can choose to
add attr for 3 or 4 fans without needing to know the nr of attr per fan.

66344aa6ad hwmon: (f71882fg) Cleanup sysfs attr creation 1/2
This patch makes a number of cleanups to the sysfs attr creation
in the f71882fg driver, this is a preparation patch for adding f71889fg
support:

* Add some comments to explain why some models need separate sysfs attr
  arrays for in / temp / fan / pwm
* Rename a number of sysfs attr arrays to make their function clearer
* Move the pwm#_auto_channels_temp attribute from the common to all
  models fan attr array to the per model auto mode pwm attr arrays, so
  that all the auto mode pwm attr are grouped together, and thus can be
  left out on models where we don't support auto pwm mode
* Put fan_beep attr in their own array, so that only auto mode pwm attr
  remain in the per model pwm sysfs attr arrays.
* Put the 4th special fan input for the f8000 in its own array, so that only
  auto mode pwm attr remain in the per model pwm sysfs attr arrays.

2d2a7cff1b ltc4215/ltc4245: Discard obsolete detect methods
There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.

So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.

This driver adds support for the hardware monitoring features of
the WM831x PMICs to the hwmon API. Monitoring is provided for
the system voltages supported natively by the WM831x, the chip
temperature, the battery temperature and the auxiliary inputs
of the WM831x.

Currently no alarms are supported, though digital comparators on
the WM831x devices would allow these to be provided.

Since the auxiliary and battery temperature input scaling depends
on the system configuration the value is reported as a voltage to
userspace.

5bed13f580 hwmon-vid: Ignore 6th VID pin of AMD family 0Fh processors
We had a report about a mainboard for AMD family 0Fh processors not
routing the 6th VID pin from the CPU to the hardware monitoring chip.

While the vendor should have wired the pin (or, failing that, should
have hardwired it to level high rather than low), the fact is that
none of these processors are currently known to operate at the lower
voltage levels which require the 6th VID pin. So, as a practical
workaround, I propose to ignore the 6th VID pin for these CPUs.

If this decision ever causes problems, we'll reconsider.

bbe5939ab1 hwmon: (abituguru3) Support multiple DMI strings per chip ID
Most known Abit motherboards have unique uguru chip IDs. However,
some "refresh" boards keep the same chip ID but have a different
DMI string. As our DMI board string matching is (necessarily)
strict, some boards were failing DMI detection, and as the old
probe method was also failing, the driver would not load.

The only known boards affected by this problem are the IP35 Pro XE
(vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to
relax the match criteria, as some boards (e.g. the AB9 Quad GT)
have different uguru chip IDs.

This patch replaces the dmi_name string with a NULL terminated
array of strings to be matched per uguru chip ID. It has been
compile and runtime tested (thanks Rune).

On newer Asus boards the "upper" limit of a sensor is encoded as
delta from the "lower" limit. Fix the driver to correctly handle
this case.

8f3128e714 lis3: add click function
The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis.  Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.

To make the configuration effective, the IRQ lines need to be set up
appropriately.  This patch also adds a way to do that from board support
code.

The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.

a002ee896d lis3: remove automatic shutdown of the device
After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision).  So let's keep the
device always on.  It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.

Moreover, since commit ef2cfc790b had been
too zealous, the device was actually never turned off anyway.  This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.

Also do more clean up with the usage of the lis3_dev global variable.

996cadb2bf hwmon: (f71882fg) Sanity check f8000 pwm settings
We depend up on the pwm_enable register (0x96) not containing any reserved
settings in various places. We were already checking to make sure there
were no reserved settings in the register for the f71862fg, this patch adds
the same checking for the f8000, while at it it also moves the code to
a more apropriate place so we don't need to check if the fan/pwm part
of the IC is enabled twice.

3fc7838a20 hwmon: (f71882fg) Cleanup f8000 pwm handling
Currently we are using separate per model sysfs attr for the 3th pwm, because
the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing
things this way was getting in the way for adding f71858fg support, so this
patch makes the pwm attr identical for all models, and instead adds a check
to store_pwm_enable() disallowing setting the 3th pwm to manual mode
on a f8000 IC.

2958b1ec6b hwmon: PCI quirk for hwmon access on MSI MS-7031 board
The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south
bridge, accessible I/O ports must be enabled explicitly. Unfortunately
the BIOS forgets to enable access to the hardware monitoring chip I/O
ports, so hardware monitoring fails.

Add a quirk enabling access to the required ports (0x295-0x296). This
is exactly what MSI's own hardware monitoring application is doing, so
it has to be the right way.
