2013-02-06hwmon: (it87) Add support for IT8771E and IT8772EGuenter Roeck1-4/+12
Assume that IT8771E and IT8772E are fully compatible with IT8728F. IT8771E support contributed by Kelly Anderson. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Jean Delvare <khali@linux-fr.org>
2012-12-20hwmon: (it87) Report thermal sensor type as Intel PECI if appropriateGuenter Roeck1-1/+2
IT8721 and IT8728 support Intel PECI temperature reporting. Each sensor can be programmed to display the temperature reported on the PECI interface. If configured for Intel PECI, the driver reported the wrong sensor type for the respective thermal sensor. Fix the code to correctly report it as "Intel PECI (6)".

2012-01-17hwmon: (it87) Add IT8728F supportJean Delvare1-3/+10
Until we get a datasheet for the IT8728F, treat it as fully compatible with the IT8721F, as it seems to work reasonably well. This closes kernel bug #27262. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Guenter Roeck <guenter.roeck@ericsson.com>
2011-07-25hwmon: (it87) Add chassis intrusion detection supportJean Delvare1-1/+2
Add chassis intrusion detection support for all supported devices, using the standard interface. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-10-28hwmon: (it87) Add support for the IT8721F/IT8758EJean Delvare1-9/+19
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.

2010-03-06hwmon: (it87) Validate auto pwm settingsJean Delvare1-0/+4
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 <khali@linux-fr.org>
2010-03-06hwmon: (it87) Add support for old automatic fan speed controlJean Delvare1-2/+25
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 <khali@linux-fr.org>
2010-03-06hwmon: (it87) Drop dead web links in documentationJean Delvare1-13/+5
Unfortunately ITE is no longer publicly providing datasheets for their IT87xxF series of chips. They may send them on request if you ask politely. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2010-03-06hwmon: (it87) Add support for beep on alarmJean Delvare1-0/+4
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 <khali@linux-fr.org>
2009-12-09hwmon: (it87) Verify the VID pin usageJean Delvare1-1/+0
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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Tested-by: Adam Nielsen <a.nielsen@shikadi.net>
2009-01-07hwmon: (it87) Add support for the ITE IT8720FJean-Marc Spaggiari1-8/+12
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. Signed-off-by: Jean-Marc Spaggiari <jean-marc@spaggiari.org> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2008-10-17hwmon: (it87) Fix thermal sensor type valuesJean Delvare1-2/+2
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.

2008-08-07hwmon: (it87) Support for 16-bit fan reading in it8705 >= rev 0x03Andrew Paprocki1-3/+3
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.

2008-08-07hwmon: (it87) Support for 16-bit fan reading in it8712 >= rev 0x07Andrew Paprocki1-4/+5
The it8712 chip supports 16-bit fan tachometers in revisions >= 0x07. Revisions >= 0x08 dropped support for 8-bit fan divisor registers. The patch enables 16-bit fan readings on all revisions >= 0x07 just like the it8716 and it8718 chips.

2007-10-10hwmon: (it87) Add support for fan4 and fan5Jean Delvare1-1/+2
Add support for the IT8716F and IT8718F fan4 and fan5. The late revisions of the IT8712F have these too but support is harder to add and nobody asked for it yet, so I didn't include it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
2007-07-19hwmon/it87: Add IT8726F supportRudolf Marek1-2/+7

2007-02-14hwmon/it87: Add PWM base frequency controlJean Delvare1-0/+10
Let the user select the base PWM frequency when using the it87 hardware monitoring driver. Different frequencies can give better control on some fans. Also update the documentation to mention the PWM frequency control files, with misc cleanups to the PWM section. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/it87: Remove the SMBus interface supportJean Delvare1-2/+13
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. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-09-29it87: Copyright updateJean Delvare1-1/+3
it87: Copyright update I think my contributions to the it87 driver over the past two years qualify me as a co-author of this driver. Also drop old comments of dubious usefulness. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-29it87: Add support for the IT8718FJean Delvare1-10/+23
it87: Add support for the IT8718F The IT8718F is a Super-I/O chip with integrated hardware monitoring functions. It is very similar to the IT8716F, so adding support to the it87 driver was pretty straightforward. The most significant difference is that the IT8718F has up to 8 VID pins, instead of 6 for the older chips. For the IT8718F, the VID value can only be read from Super-I/O space. Userspace support is already in lm_sensors SVN (to be soon released as 2.10.1.) Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2006-09-29it87: Add support for the IT8716FJean Delvare1-11/+29
it87: Add support for the IT8716F The IT8716F is a Super-I/O chip with integrated hardware monitoring functions. It is very similar to the IT8712F, so adding support to the it87 driver was pretty straightforward. The most significant change here is that the IT8716F has 16-bit fan speed counters, so the user no more needs to tweak the fan clock dividers to get the best readings. Userspace support is already in lm_sensors SVN (to be soon released as 2.10.1.) Thanks to Stian Oksavik, Olivier Nicolas, Prakash Punnoor and Juergen Kilb for testing the early versions of this patch. Thanks also to ITE for providing datasheets and answering my questions.

2006-02-06[PATCH] hwmon: Fix reboot on it87 driver loadJean Delvare1-1/+1
Only scan I2C address 0x2d. This is the default address and no IT87xxF chip was ever seen on I2C at a different address. These chips are better accessed through their ISA interface anyway. This fixes bug #5889, although it doesn't address the whole class of problems. We'd need the ability to blacklist arbitrary I2C addresses on systems known to contain I2C devices which behave badly when probed. Plan the I2C interface for removal as well. If nobody complains within a year, it will confirm my impression that the I2C interface isn't actually needed by anyone.

2005-10-29[PATCH] hwmon: Drop legacy ISA address support from it87Jean Delvare1-4/+4
Drop legacy ISA address support from the it87 driver. All supported chips are Super-I/O chips, so the device ISA address can be safely read from Super-I/O space rather than blindly assumed. Two nearby inaccurate documentation statements have been fixed as well: * The IT8705F doesn't have an SMBus interface. * The SiS950 doesn't have a distinct prefix.

2005-07-12[PATCH] I2C: Move hwmon drivers (3/3)Jean Delvare1-0/+96
