hwmon: (it87) Add chassis intrusion detection support

2011-07-25T19:46:10+00:00

Add chassis intrusion detection support for all supported devices,
using the standard interface.

hwmon: (it87) Add support for the IT8721F/IT8758E

2010-10-28T18:31:51+00:00

Add support for the IT8721F/IT8758E. These new chips differ from the
older IT87xxF chips in the following ways:
* ADC LSB is 12 mV instead of 16 mV.
* PWM values are 8-bit instead of 7-bit.
There are other minor changes we don't have to care about in the
driver.

Another change is that we will handle internal voltage scaling in the
driver instead of delegating the work to user-space.

hwmon: (it87) Validate auto pwm settings

2010-03-05T21:17:21+00:00

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.

hwmon: (it87) Add support for old automatic fan speed control

2010-03-05T21:17:21+00:00

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.

hwmon: (it87) Drop dead web links in documentation

2010-03-05T21:17:21+00:00

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

hwmon: (it87) Add support for beep on alarm

2010-03-05T21:17:17+00:00

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.

hwmon: (it87) Verify the VID pin usage

2009-12-09T19:35:47+00:00

The VID input pins can alternatively be used as GPIOs. Make sure we
have at least 4 pins used for VID, otherwise don't bother reading and
exposing VID.

hwmon: (it87) Add support for the ITE IT8720F

2009-01-07T15:37:32+00:00

Allow it87.c to handle IT8720 chipset like IT8718 in order to
retrieve voltage, temperatures and fans speed from sensors
tools. Also updating the related documentation.

hwmon: (it87) Fix thermal sensor type values

2008-10-17T15:51:16+00:00

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.

hwmon: (it87) Support for 16-bit fan reading in it8705 >= rev 0x03

2008-08-06T20:41:06+00:00

The it8705 chip supports 16-bit fan tachometers in revisions at least
>= 0x03 (Version G). This patch enables 16-bit fan readings on all
revisions >= 0x03 just like the it8712, it8716, and it8718 chips.
