Add basic support for the ADT7411. Reads out all conversion results (via I2C,
SPI yet missing) and allows some on-the-fly configuration. Tested with a
custom board.Signed-off-by: Sascha Hauer

Before switching to automatic fan control mode, make sure that all the
trip points make sense. Otherwise, the control loop could lead to
weird fan behavior.Signed-off-by: Jean Delvare
-
Add support for the automatic fan speed control interface as
implemented by IT8705F chips up to revision F and IT8712F chips up to
revision G. This implementation fits very well in our standard sysfs
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.Signed-off-by: Jean Delvare

Unfortunately ITE is no longer publicly providing datasheets for their
IT87xxF series of chips. They may send them on request if you ask

The IT87xxF chips support beeping on alarm, if properly wired and
configured. There is one control bit for each input type (temperature,
fan, voltage.) Let the user see and change them.Signed-off-by: Jean Delvare

Tested successfully with an ADM1032 chip on its evaluation board. It
should work fine with all other chips as well.At this point this is more of a proof-of-concept, we don't do anything
terribly useful on SMBus alert: we simply log the event. But this could
later evolve into libsensors signaling so that user-space applications
can take an appropriate action.Signed-off-by: Jean Delvare

Add control of fan minimum turn-on output levels, decoupling it from the
fan turn-off output level. Add control of rate of change of fan output
level. These in turn allow lower turn-off rotor speed and smoother
transitions for better thermal and acoustic control authority. Add
support for constant fan speed and proportional-response operations modes.[akpm@linux-foundation.org: coding-style fixes]

Add support for the ADT7473 to the adt7475 driver, and mark the

This adds support for the Fintek f71889fg to the f71882fg driver,
many thanks to Gerd v. Egidy for providing (remote) access to a
machine which such an ic.Note that this bit of the patch:
- val = SENSORS_LIMIT(val, 0, 255);
+
+ if (data->type == f71889fg)
+ val = SENSORS_LIMIT(val, -128, 127);
+ else
+ val = SENSORS_LIMIT(val, 0, 127);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
0, so the previous behaviour which allowed setting temp zone limits > 127
was not correct.Signed-off-by: Hans de Goede

This module parameter is there to workaround broken BIOS. I'm not even
sure if it was used in the past 5 years, and it gets in the way of
converting the driver to the MFD infrastructure. So tell the users how
they can do the same from user-space.Signed-off-by: Jean Delvare

There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
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
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.Signed-off-by: Jean Delvare

Allows users who use an IDE driver for their disk to use hpfall without
having to modify the source. By default /dev/sda is used.
Suggested by Christian Thaeter in http://lkml.org/lkml/2009/3/25/505.While we're add it, improve error message if opening /dev/freefall fails.

Improve the example code to be at least useable, as in not causing
harm (as shown below). Code can still be improved further, but this
adds some basic safeguards.1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself!
Since the Program sits and waits most of the time it becomes very likely
swapped out. If it gets woken up when the laptop drops from the table
while it is swapped out it actually triggers harddrive activity!2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty).
3. Give hpfall realtime priority.
Should give a chance that it has less latency when woken up.Signed-off-by: Christian Thaeter

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices. This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket. This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.[akpm@linux-foundation.org: remove default-y]
