Description
-----------
Fintek F718xxFG/F8000 Super I/O chips include complete hardware monitoring
capabilities. They can monitor up to 9 voltages (3 for the F8000), 4 fans and
3 temperature sensors.
These chips also have fan controlling features, using either DC or PWM, in
three different modes (one manual, two automatic).
The driver assumes that no more than one chip is present, which seems
reasonable.
Monitoring
----------
The Voltage, Fan and Temperature Monitoring uses the standard sysfs
interface as documented in sysfs-interface, without any exceptions.
Fan Control
-----------
Both PWM (pulse-width modulation) and DC fan speed control methods are
supported. The right one to use depends on external circuitry on the
motherboard, so the driver assumes that the BIOS set the method
properly.
There are 2 modes to specify the speed of the fan, PWM duty cycle (or DC
voltage) mode, where 0-100% duty cycle (0-100% of 12V) is specified. And RPM
mode where the actual RPM of the fan (as measured) is controlled and the speed
gets specified as 0-100% of the fan#_full_speed file.
Since both modes work in a 0-100% (mapped to 0-255) scale, there isn't a
whole lot of a difference when modifying fan control settings. The only
important difference is that in RPM mode the 0-100% controls the fan speed
between 0-100% of fan#_full_speed. It is assumed that if the BIOS programs
RPM mode, it will also set fan#_full_speed properly, if it does not then
fan control will not work properly, unless you set a sane fan#_full_speed
value yourself.
Switching between these modes requires re-initializing a whole bunch of
registers, so the mode which the BIOS has set is kept. The mode is
printed when loading the driver.
Three different fan control modes are supported; the mode number is written
to the pwm#_enable file. Note that not all modes are supported on all
chips, and some modes may only be available in RPM / PWM mode on the F8000.
Writing an unsupported mode will result in an invalid parameter error.
* 1: Manual mode
You ask for a specific PWM duty cycle / DC voltage or a specific % of
fan#_full_speed by writing to the pwm# file. This mode is only
available on the F8000 if the fan channel is in RPM mode.
* 2: Normal auto mode
You can define a number of temperature/fan speed trip points, which % the
fan should run at at this temp and which temp a fan should follow using the
standard sysfs interface. The number and type of trip points is chip
depended, see which files are available in sysfs.
Fan/PWM channel 3 of the F8000 is always in this mode!
* 3: Thermostat mode (Only available on the F8000 when in duty cycle mode)
The fan speed is regulated to keep the temp the fan is mapped to between
temp#_auto_point2_temp and temp#_auto_point3_temp.
Both of the automatic modes require that pwm1 corresponds to fan1, pwm2 to
fan2 and pwm3 to fan3.

Description
-----------
The LTC4245 controller allows a board to be safely inserted and removed
from a live backplane in multiple supply systems such as CompactPCI and
PCI Express.
Usage Notes
-----------
This driver does not probe for LTC4245 devices, due to the fact that some
of the possible addresses are unfriendly to probing. You will need to use
the "force" parameter to tell the driver where to find the device.
Example: the following will load the driver for an LTC4245 at address 0x23
on I2C bus #1:
$ modprobe ltc4245 force=1,0x23
Sysfs entries
-------------
The LTC4245 has built-in limits for over and under current warnings. This
makes it very likely that the reference circuit will be used.
This driver uses the values in the datasheet to change the register values
into the values specified in the sysfs-interface document. The current readings
rely on the sense resistors listed in Table 2: "Sense Resistor Values".
