2006-12-12hwmon: New AMS hardware monitoring driverStelian Pop
This driver adds support for the Apple Motion Sensor (AMS) as found in 2005 revisions of Apple PowerBooks and iBooks. It implements both the PMU and I2C variants. The I2C driver and mouse emulation is based on code by Stelian Pop, while the PMU driver has been developped by Michael Hanselmann. HD parking support will be added later. Various people contributed fixes to this driver, including Aristeu Sergio Rozanski Filho and Jean Delvare.

2006-12-12hwmon/f71805f: Fix the device address decodingJean Delvare
The lowest 3 bits are ignored, and the chip decodes all 8 addresses, not only the 2 it needs. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Always create all fan inputsJean Delvare
Fans can be hotplugged, so we should create sysfs file even for fans which are disabled at driver load time. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Add support for the Fintek F71872F/FG chipJean Delvare
Add support for the Fintek F71872F/FG Super-I/O chip. It is basically the same as the Fintek F71805F/FG as far as hardware monitoring is concerned, with two additional internal voltages monitored (VSB and battery), and 6 VID inputs (not yet supported.) To make things a bit more confusing, two of the voltage input pins (in4 and in8) can be used for other functions. The driver reads the pin configuration from the Super-I/O configuration space to decide whether it must create interface files for these inputs or not. Many thanks to Nikolay Derkach for testing the early iterations of this code and reporting bugs. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon: New PC87427 hardware monitoring driverJean Delvare
This is a new hardware monitoring driver for the National Semiconductor PC87427 Super-I/O chip. It only supports fan speed monitoring for now, while the chip can do much more. Thanks to Amir Habibi at Candelis for setting up a test system, and to Michael Kress for testing several iterations of this driver. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/it87: Remove the SMBus interface supportJean Delvare
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>

2006-12-12hwmon/hdaps: Move the DMI detection data to .dataJean Delvare
Move the DMI detection data from .text to .data. We really don't want that amount of data on the stack. Also refactor the macros used to generate the detection data, the vendor becomes a parameter. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Robert Love <rlove@rlove.org>
2006-12-12hwmon/pc87360: Autodetect the VRM versionJim Cromie
pc87360 currently hardcodes vrm = 90 (2.4 vintage). Update it to use newer code in hwmon-vid which reads cpuid to determine the correct vid. Signed-off-by: Jim Cromie <jim.cromie@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Add support for "speed mode" fan speed controlJean Delvare
In "speed mode", the user specifies a target fan speed (in RPM) and the chip automatically adjusts the PWM duty cycle (or DC output level) to reach this target. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Support DC fan speed control modeJean Delvare
In DC mode, the pwmN_freq files are not created. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Let the user adjust the PWM base frequencyJean Delvare
Different frequencies can give better results depending on the exact fan model used. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Add manual fan speed controlJean Delvare
pwmN files are writable only in manual fan speed control mode. In automatic fan speed control modes, they are read-only and report the duty cycle chosen by the chip. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2006-12-12hwmon/f71805f: Store the fan control registersJean Delvare
So far we were only extracting the fan skip bit from the fan control registers, but we'll soon need more bits so better store the whole register values. Signed-off-by: Jean Delvare <khali@linux-fr.org>

hwmon: Fix unchecked return status, batch 4 Fix up some hwmon drivers so that they no longer ignore return status from device_create_file(). Note: f71805f actually checked the status from device_create_file already. However it did not remove the files on device destruction. It was also an opportunity to use sysfs_create/remove_group instead of hand-made loops. This makes the changes much more important but I think the result is worth it.

pc87360: Check for error on sysfs files creation Use sysfs_create_group() for 2 sensor-types which are chip-model invariant, i.e. all-or-nothing attribute groups.

2006-09-28hwmon: New driver for the VIA VT1211Juerg Haefliger
hwmon: New driver for the VIA VT1211 This is a new driver for the VIA VT1211 Super-IO chip. It is a rewrite of the existing vt1211 driver (by Mark D. Studebaker and Lars Ekman) which has been around for a while but never made it into the main kernel tree. It is implemented as a platform driver and therefore requires lm_sensors 2.10.1 to function properly.
