| * hwmon: WM831x PMIC hardware monitoring driverMark Brown2009-09-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver adds support for the hardware monitoring features of the WM831x PMICs to the hwmon API. Monitoring is provided for the system voltages supported natively by the WM831x, the chip temperature, the battery temperature and the auxiliary inputs of the WM831x. Currently no alarms are supported, though digital comparators on the WM831x devices would allow these to be provided. Since the auxiliary and battery temperature input scaling depends on the system configuration the value is reported as a voltage to userspace.

* hwmon: Add LTC4215 driverIra Snyder2009-04-01
| | | | | | | | | | | | | | | | | | | | | | | 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.

* Move the pcf8591 driver to hwmonJean Delvare2009-03-30
| | | | | | | | | | | | | | 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>

* LIS3LV02Dx Accelerometer driverPavel Machek2008-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* hwmon: (it87) Fix thermal sensor type valuesJean Delvare2008-10-17
| | | | | | | | | | | | | | | 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.

| | | | | | | | These Maxim chips are similar to MAX6657 but use unsigned temperature values to allow for readings up to 145 degrees. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
* hwmon: (lm90) Support ADT7461 in extended modeNate Case2008-10-17
| | | | | | | | | | Support ADT7461 in extended temperature range mode, which will change the range of readings from 0..127 to -64..191 degC. Adjust the register conversion functions accordingly.

* hwmon: (lm90) Update datasheet linksJean Delvare2008-10-17
| | | | | | | | | Update the links to the datasheet of some of the devices supported by the lm90 driver. Also remove the links from the driver itself, so that we don't have to update them twice each time they change.

* hwmon: (lm90) Support the extra resolution bits of MAX6657Jean Delvare2008-10-17
| | | | | | | | | The Maxim MAX6657, MAX6658 and MAX6659 have extra resolution bits for the local temperature measurement. Let the lm90 driver read them and export them to user-space. Signed-off-by: Jean Delvare <khali@linux-fr.org> Acked-by: Martyn Welch <martyn.welch@gefanuc.com>
