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.

2009-09-21trivial: doc: hpfall: reduce risk that hpfall can do harmChristian Thaeter
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.

2009-09-19hwmon driver for ACPI 4.0 power metersDarrick J. Wong
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.

2009-09-17hwmon: WM831x PMIC hardware monitoring driverMark Brown
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.

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>

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.

2008-10-26hwmon: (lm90) Add support for the LM99 16 degree offsetJean Delvare
The LM99 differs from the LM86, LM89 and LM90 in that it reports remote temperatures (temp2) 16 degrees lower than they really are. So far we have been cheating and handled this in userspace but it really should be handled by the driver directly.

2008-10-17hwmon: (w83781d) Additional information about AS99127F PWMJean Delvare
This information was provided in lm-sensors ticket #2350: http://www.lm-sensors.org/ticket/2350 This is IMHO still not enough to be able to safely implement fan control support for the AS99127F, but this is valuable information so I am adding it to the documentation.
