This driver adds support for the Apple Motion Sensor (AMS) as found in 2005
revisions of Apple PowerBooks and iBooks.  It implements both the PMU and
I2C variants.  The I2C driver and mouse emulation is based on code by
Stelian Pop, while the PMU driver has been developped by Michael Hanselmann.
HD parking support will be added later.

Various people contributed fixes to this driver, including
Aristeu Sergio Rozanski Filho and Jean Delvare.

Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the
same as the Fintek F71805F/FG as far as hardware monitoring is concerned,
with two additional internal voltages monitored (VSB and battery), and 6
VID inputs (not yet supported.)

To make things a bit more confusing, two of the voltage input pins (in4
and in8) can be used for other functions. The driver reads the pin
configuration from the Super-I/O configuration space to decide whether
it must create interface files for these inputs or not.

Many thanks to Nikolay Derkach for testing the early iterations of this
code and reporting bugs.

This is a new hardware monitoring driver for the National Semiconductor
PC87427 Super-I/O chip. It only supports fan speed monitoring for now,
while the chip can do much more.

Thanks to Amir Habibi at Candelis for setting up a test system, and to
Michael Kress for testing several iterations of this driver.

This interface was useless as the LPC ISA-like interface is always
available, is faster, and is more reliable. This cuts the driver
size by some 20%.

This change is also required to later convert the it87 driver to a
platform driver, so that we can get rid of i2c-isa in a near future.

In "speed mode", the user specifies a target fan speed (in RPM) and the
