Darrick J. Wong 89fac11cb3 adt7470: make automatic fan control really work
It turns out that the adt7470's automatic fan control algorithm only works
when the temperature sensors get updated.  This in turn happens only when
someone tells the chip to read its temperature sensors.  Regrettably, this
means that we have to drive the chip periodically.

Darrick J. Wong c0b4e3ab0c adt7462: new hwmon driver
New driver to play with.  As Jean mentioned a couple of years ago, this
chip is a beast with odd combinations of 8 fans, 4 temperatures, and 13
voltage sensors.  This driver has been tested on an IntelliStation Z30.

Pavel Machek 455fbdd376 LIS3LV02Dx Accelerometer driver
This adds a driver to the accelerometer sensor found in several HP
laptops (under the commercial names of "HP Mobile Data Protection System
3D" and "HP 3D driveguard").  It tries to have more or less the same
interfaces as the hdaps and other accelerometer drivers: in sysfs and as
a joystick.

This driver was first written by Yan Burman.  Eric Piel has updated it
and slimed it up (including the removal of an interface to access to the
free-fall feature of the sensor because it is not reliable enough for
now).  Pavel Machek removed few more features and switched locking from
semaphore to mutex.

Several people have contributed to the database of the axes.

Jean Delvare 97ae60bb38 hwmon: (lm90) Add support for the LM99 16 degree offset
The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.

Jean Delvare 4ed1077953 hwmon: (it87) Fix thermal sensor type values
The it87 driver doesn't follow the standard sensor type values as
documented in Documentation/hwmon/sysfs-interface. It uses value 2 for
thermistors instead of value 4. This causes "sensors" to tell the user
that the chip is setup for a transistor while it is actually setup for
a thermistor.

Using value 4 for thermistors solves the problem. For compatibility
reasons, we still accept value 2 but emit a warning message so that
users update their configuration files.

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.
