* hwmon: (adm1031) Fix register overwrite in set_fan_div()Jean Delvare2008-02-07
| | | | | | | | | | | | | | Don't rely on the register cache when setting a new fan clock divider. For one thing, the cache might not have been initialized at all if the driver has just been loaded. For another, the cached values may be old and you never know what can happen in the driver's back. Also invalidate the cache instead of trying to adjust the measured fan speed: the whole point of changing the clock divider is to get a better reading.

| | | | | | | | | On the ADM1026, pins 27 and 28 can be used for two different functions: either temp3, or in8+in9.

* hwmon: Let the user override the detected Super-I/O device IDJean Delvare2008-02-07
| | | | | | | | | | | | | | | | | | | | | | | While it is possible to force SMBus-based hardware monitoring chip drivers to drive a not officially supported device, we do not have this possibility for Super-I/O-based drivers. That's unfortunate because sometimes newer chips are fully compatible and just forcing the driver to load would work. Instead of that we have to tell the users to recompile the kernel driver, which isn't an easy task for everyone. So, I propose that we add a module parameter to all Super-I/O based hardware monitoring drivers, letting advanced users force the driver to load on their machine. The user has to provide the device ID of a supposedly compatible device. This requires looking at the source code or a datasheet, so I am confident that users can't randomly force a driver without knowing what they are doing. Thus this should be relatively safe. As you can see from the code, the implementation is pretty simple and unintrusive.

* hwmon: (lm90) Use generic i2c reads during detectionJean Delvare2008-02-07
| | | | | | | | | | | As indirectly reported by Olof Johansson, the lm90 driver uses a custom i2c read function even during detection, at which point we don't know yet what device we're talking with. It would make more sense to only use the generic i2c read function at this point, so that we don't log irrelevant errors on misdetection.

* hwmon: (gl518sm) Fix the reported fan speedJean Delvare2008-02-07
| | | | | | | | | | | | The fan speeds reported by the gl518sm driver are twice as much as they should. It's currently reporting the number of pulses per minute, not rotations per minute, while typical fans emit two pulses per rotation. This explains why all reports with this driver had very high speed values (between 9000 to 12000 RPM). Odd that nobody ever actually complained about this bug.

* hwmon: (it87) request only Environment Controller portsBjorn Helgaas2008-01-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IT8705F and related parts are Super I/O controllers that contain many separate devices. Some BIOSes describe IT8705F I/O port usage under a motherboard device (PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294. The it87 driver supports only the Environment Controller, which requires only two ISA ports, but it used to request an eight-port range. If that range exceeds a range reported by the BIOS, as 0x290-0x297 would, the request fails, and the it87 driver cannot claim the device. This patch makes the it87 driver request only the two ports used for the Environment Controller device. Systems where this problem has been reported: Gigabyte GA-K8N Ultra 9 Gigabyte M56S-S3 Gigabyte GA-965G-DS3 Kernel bug reports: http://bugzilla.kernel.org/show_bug.cgi?id=9514 http://lkml.org/lkml/2007/12/4/466 Related change: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=a7839e960675b549f06209d18283d5cee2ce9261 The patch above increases the number of PNP port resources we support.

* HWMON: coretemp, suspend fixRafael J. Wysocki2007-12-04
| | | | | | | | | | | | | | | | It's not permitted to unregister a device after devices have been suspended.
