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.

Move the DMI detection data from .text to .data. We really don't want

Also refactor the macros used to generate the detection data, the

In "speed mode", the user specifies a target fan speed (in RPM) and the
chip automatically adjusts the PWM duty cycle (or DC output level) to
reach this target.

pwmN files are writable only in manual fan speed control mode.
In automatic fan speed control modes, they are read-only and

So far we were only extracting the fan skip bit from the

hwmon: New driver for the VIA VT1211
This is a new driver for the VIA VT1211 Super-IO chip. It is a rewrite
of the existing vt1211 driver (by Mark D. Studebaker and Lars Ekman)
which has been around for a while but never made it into the main
kernel tree.
It is implemented as a platform driver and therefore requires
lm_sensors 2.10.1 to function properly.

The IT8718F is a Super-I/O chip with integrated hardware monitoring

is that the IT8718F has up to 8 VID pins, instead of 6 for the older
