While testing an ADC121S021 in an embedded board with a S3C2142 SoC (ARM
core), I have found that the 'adcxx' driver does not handle correctly
single channel ADCs from this chip family. For single channel chips you
must only issue one read transfer for correct measurement.

Add support for the automatic fan speed control interface as
implemented by IT8705F chips up to revision F and IT8712F chips up to

interface.
I implemented the old and not the new interface because the only chip
I have at hand is an old one, and the new interface is more difficult
to map to the standard sysfs interface. Adding support later should be
possible though, if someone with a supported chip is interested.

At this point this is more of a proof-of-concept, we don't do anything

Different motherboards have different PNP declarations for
W83781D/W83782D chips. Some declare the whole range of I/O ports (8
ports), some declare only the useful ports (2 ports at offset 5) and
some declare fancy ranges, for example 4 ports at offset 4. To
properly handle all cases, request all ports individually for probing.
After we have determined that we really have a W83781D or W83782D
chip, the useful port range will be requested again, as a single
block.
I did not see a board which needs this yet, but I know of one for lm78

The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the
for loops that use this as a limit count are of the typical form, "for
(n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages
w/o missing the last one it is necessary for the count to be one greater
than it is. (Specifically, you will miss the +1.5V 3GPIO input with count
= 12 vs. 13.)

Report output values as 1/1000 of earth gravity.
Output values from lis3 can be read from sysfs position entry and from
input device. Input device can be accessed as event device and as
joystick device. Joystick device can be in two modes. Meaning of the
output values varies from case to case depending on the chip type and
configuration (scale). Only joystick interface in JS_CORR_BROKEN mode
returned somehow similar output values in different configurations.
Joystick device is in that state by default in case of lis3.
Position sysfs entry, input event device and raw joystick device have been
little bit broken since meaning of the output values has been varied
between 12 and 8 bit devices. Applications which relayed on those methods
failed if the chip is different than the expected one.
This patch converts output values to mean similar thing in different
configurations. Both 8 and 12 bit devices reports now same acceleration
values. If somebody implements full scale support to the driver, output
values will still mean the same. Scaling factor and input device range
must be updated in that case.
Joystick interface in JS_CORR_BROKEN mode is not touched by this patch.
All other interfaces have different scale after this change. For 12 bit
device scaling factor is 0.977 which keeps scaled and unscaled values are
quite close to each others. For 8 bit device, scaled values are 18 times
bigger than unscaled values.

Implement selftest feature as specified by chip manufacturer. Control:
read selftest sysfs entry
Response: "OK x y z" or "FAIL x y z"
where x, y, and z are difference between selftest mode and normal mode.
Test is passed when values are within acceptance limit values.
Acceptance limits are provided via platform data. See chip spesifications
for acceptance limits. If limits are not properly set, OK / FAIL decision
is meaningless. However, userspace application can still make decision
based on the numeric x, y, z values.
Selftest is meant for HW diagnostic purposes. It is not meant to be
called during normal use of the chip. It may cause false interrupt
events. Selftest mode delays polling of the normal results but it doesn't
cause wrong values. Chip must be in static state during selftest. Any

It is possible to bypass the voltage attenuators on the +2.5V, Vccp,
+5V and +12V voltage monitoring inputs. This is useful to connect
other voltage channels than the ones the monitoring chip was
originally designed for. When this feature is enabled, we must not
include the scaling factors in our computations.

This adds support for the Fintek f71889fg to the f71882fg driver,

+ if (data->type == f71889fg)
+ val = SENSORS_LIMIT(val, -128, 127);
+ else

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

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.

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.

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

The static code scanner "Parfait" reported this because pwm_config is
only 3 bytes - pwm_config[3] is out of range.
Since this code path is never called with ix == 3 (the device has no PWM4
output) this doesn't change anything in practice. But to encourage
testing with Parfait, lets make the warning go away...

On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt. This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the
memorized logical state, in effect bringing back the accelerometer and
backlight to the state prior to suspend. Works for both suspend to ram
and hibernation. The patch has zero effect on the running state.

Occasionally it is helpful to be able to turn a temperature sensor off
(for example if it's making unwanted electrical noise). This patch
adds a sysfs node to put any adm1021 compatible device into low power mode.

The ADM1023 temperature sensor supports higher resolution for its external
sensor (sensitivity of 1/8 deg C). This patch makes this higher
resolution available through the appropriate temperature sysfs nodes.
Curiously, this functionality was available in the 2.4 kernel driver (but
formatted in a less helpful manner).

This enabled power management functions for the SPI transport layer of the
lis3 devices. The device's suspend mode is only entered in case no wakeup
threshold has been given. In this case, the device is supposed to wake up
the system and must thus not be put to deep sleep.

Enable the coretemp driver on an Intel Atom.
I'm not sure if the readings are correct, however - on my 330, the driver
reports values between 27 and 41 °C (with core1 being about 8°C hotter
than core0, given the same load). Maybe the maximum temperature of 100 °C
is wrong for Atom CPUs.

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.

The Winbond/Nuvoton WPCD377I is the reduced version of a Super-I/O
which emulates the National Semiconductor LM96000 hardware monitoring
chips, but without the hardware monitoring part. Instead of plain
disabling the emulation, the vendor left the emulated chip visible,
but all monitored values are always zero. This is rather confusing for
the users. So detect this case and refuse to bind to such fake chips.
