2009-06-15hwmon: (f71882fg) Add support for the F71858FHans de Goede
Add support for the hwmon part of the Fintek F71858FG superio IC to the f71882fg driver. Many thanks to Jelle de Jong for lending me a motherboard with this superio on it. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2009-06-15hwmon: (w83627ehf) Add W83627DHG-P supportJean Delvare
Add support for the new incarnation of the Winbond/Nuvoton W83627DHG chip known as W83627DHG-P. It is basically the same as the original W83627DHG with an additional automatic can speed control mode (not supported by the driver yet.)

This controller can be found on the D-Link DNS-323 for instance, where it is to be configured via static i2c_board_info in the board-specific mach-orion/dns323-setup.c; this driver supports only the new-style driver model.

2009-04-01hwmon: Add LTC4215 driverIra Snyder
Add Linux support for the Linear Technology LTC4215 Hot Swap controller I2C monitoring interface. I have tested the driver with my board, and it appears to work fine. With the power supplies disabled, it reads 11.93V input, 1.93V output, no current and no power. With the supplies enabled, it reads 11.93V input, 11.98V output, no current, no power. I'm not drawing any current at the moment, so this is reasonable. The value in the sense register never reads anything except 0, so I expect to get zero from the current and power calculations. I didn't attempt to support changing any of the chip's settings or enabling the FET. I'm not sure even how to do that and still fit within the hwmon framework. :) Signed-off-by: Ira W.

2009-03-30Move the pcf8591 driver to hwmonJean Delvare
Directory drivers/i2c/chips is going away, so drivers there must find new homes. For the pcf8591 driver, the best choice seems to be the hwmon subsystem. While the Philips PCF8591 device isn't a typical hardware monitoring chip, its DAC interface is compatible with the hwmon one, so it fits somewhat. If a better subsystem is ever created for ADC/DAC chips, the driver could be moved there. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Aurelien Jarno <aurelien@aurel32.net>
2009-03-30hwmon: (w83627ehf) Add support for W83667HGGong Jun
Add initial support for the Nuvoton W83667HG chip to the w83627ehf driver. It has been tested on ASUS P5QL PRO by Gong Jun. At the moment there is still a usability issue which is that only in6 or temp3 can be present on the W83667HG, so the driver shouldn't expose both. This will be addressed later.

2009-02-18hp accelerometer: add freefall detectionPavel Machek
This adds freefall handling to hp_accel driver. According to HP, it should just work, without us having to set the chip up by hand. hpfall.c is example .c program that parks the disk when accelerometer detects free fall. It should work; for now, it uses fixed 20seconds protection period.

2008-11-12LIS3LV02Dx Accelerometer driverPavel Machek
This adds a driver to the accelerometer sensor found in several HP laptops (under the commercial names of "HP Mobile Data Protection System 3D" and "HP 3D driveguard"). It tries to have more or less the same interfaces as the hdaps and other accelerometer drivers: in sysfs and as a joystick. This driver was first written by Yan Burman. Eric Piel has updated it and slimed it up (including the removal of an interface to access to the free-fall feature of the sensor because it is not reliable enough for now). Pavel Machek removed few more features and switched locking from semaphore to mutex. Several people have contributed to the database of the axes.

2008-10-17hwmon: (it87) Fix thermal sensor type valuesJean Delvare
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.

Implement the standard PWM frequency interface: pwm[1-*]_freq in units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq in units of 0.1 Hz. The old naming was not only non-standard, it was also confusing, because it suggested that the frequency value only applied in automatic fan speed mode, which isn't true.

2008-08-06hwmon: (w83627hf) Drop reset module parameterJean Delvare
Drop the reset parameter of the w83627hf driver. It seems it wasn't that useful. It was dropped from the Linux 2.4 version of this driver back in July 2004. The only users who have reported that they were still using this parameter, needed it to switch the chip from automatic fan speed control back to manual mode. Now that the driver creates pwmN_enable sysfs files, users will be able to use these files instead, which is way less agressive.
