2007-02-14hwmon/vt1211: Add probing of alternate config index portJuerg Haefliger
The configuration index port of the vt1211 can be accessed at two different addresses 0x2e or 0x4e, depending on pin strappings. This patch adds support to scan both addresses during module initialization. Signed-off-by: Juerg Haefliger <juergh@gmail.com> Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-14hwmon/f71805f: Fix a race conditionJean Delvare
I think I introduced a potential race condition bug with commit 51c997d80e1f625aea3426a8a9087f5830ac6db3. I didn't realize it back then, but platform_device_put and platform_device_release both appear to free the platform data associated with the device. This makes an explicit kfree redundant at best, and maybe even racy, as it might occur while someone still holds a reference to the platform device. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-14hwmon/abituguru: Fix unchecked return statusHans de Goede
Fix an unused return value warning for the abituguru driver. Also make sure the sysfs files are created before we register with the hwmon class, and delete the sysfs files on driver removal. Signed-off-by: Hans de Goede <j.w.r.degoede@hhs.nl> Signed-off-by: Jean Delvare <khali@linux-fr.org>

2007-02-14hwmon: Use subsys_initcallDavid Brownell
Subsystem infrastructure should normally register with "subsys_initcall", so that it's available to drivers that may need to initialize early. This patch updates "hwmon" to do so. It's common for embedded systems to have multifunction chips with hardware monitoring interfaces, and to have those chips be used during system bringup ... before a normal "module_init" would kick, or maybe just linked so they'd init before hwmon.

2007-02-14hwmon: Cleanup a bogus legacy commentJean Delvare
Cleanup a bogus legacy comment that has been replicated to many hardware monitoring drivers. Signed-off-by: Jean Delvare <khali@linux-fr.org>
2007-02-14hwmon: Simplify the locking model of two driversJean Delvare
Many hardware monitoring drivers use two different mutexes, one to protect their per-device data structure, and one to protect the access to the device registers. These mutexes are essentially redundant, as the drivers are transfering values between the device registers and the data cache, so they almost always end up holding both mutexes at the same time. Using a single mutex will make the code more simple and faster. I am changing only two of the affected drivers here, the authors of the other affected drivers are welcome to submit similar patches if they want. Signed-off-by: Jean Delvare <khali@linux-fr.org>

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: Always create all fan inputsJean Delvare

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.

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/f71805f: Add support for "speed mode" fan speed controlJean Delvare

2006-12-12hwmon/f71805f: Add manual fan speed controlJean Delvare
