* hwmon/w83627ehf: Preserve speed reading when changing fan minJean Delvare2007-07-19
| | | | | | | | | The w83627ehf driver changes the fan clock divider automatically when a new min fan speed is set. It is supposed to preserve the fan speed reading while doing so, bug doesn't really. Fix it. Signed-off-by: Jean Delvare <khali@linux-fr.org> Signed-off-by: Mark M. Hoffman <mhoffman@lightlink.com>
* hwmon/w83627ehf: Don't redefine REGION_OFFSETJean Delvare2007-04-24
| | | | | | | | | | On ia64, kernel headers define REGION_OFFSET so we can't use that. Reported by Andrew Morton.

* hwmon/w83627ehf: Fix the fan5 clock divider writeJean Delvare2007-04-17
| | | | | | | | | | | | | | | | | | | | | | Users have been complaining about the w83627ehf driver flooding their logs with debug messages like: w83627ehf 9191-0a10: Increasing fan 4 clock divider from 64 to 128 or: w83627ehf 9191-0290: Increasing fan 4 clock divider from 4 to 8 The reason is that we failed to actually write the LSB of the encoded clock divider value for that fan, causing the next read to report the same old value again and again. Additionally, the fan number was improperly reported, making the bug harder to find.

* [PATCH] I2C: Remove .owner setting from i2c_driver as it's no longer neededGreg Kroah-Hartman2006-01-06
| | | | | | | | | | Now that i2c_add_driver() doesn't need the module owner to be set by hand, we can delete it from the drivers. This patch catches all of the drivers that I found in the current tree (if a driver sets the .owner by hand, it's not a problem, just not needed.)

* [PATCH] hwmon: Fix w83627ehf/hf vs PNPACPI conflict (bug #4014)Petr Vandrovec2005-10-28
| | | | | | | | | | | | | | | | | | | | | | | | This patch changes w83627hf and w83627ehf drivers to reserve only ports 0x295-0x296, instead of full 0x290-0x297 range. While some other sensors chips respond to all addresses in 0x290-0x297 range, Winbond chips respond to 0x295-0x296 only (this behavior is implied by documentation, and matches behavior observed on real systems). This is not problem alone, as no BIOS was found to put something at these unused addresses, and sensors chip itself provides nothing there as well. But in addition to only respond to these two addresses, also BIOS vendors report in their ACPI-PnP structures that there is some resource at I/O address 0x295 of length 2. And when later this hwmon driver attempts to request region with base 0x290/length 8, it fails as one request_region cannot span more than one device. Due to this we have to ask only for region this hardware really occupies, otherwise driver cannot be loaded on systems with ACPI-PnP enabled.

* [PATCH] I2C: refactor message in i2c_detach_clientJean Delvare2005-09-05
| | | | | | | | | | | | We could refactor the error message 34 different i2c drivers print if i2c_detach_client() fails in this function itself. Saves quite a few lines of code. Documentation is updated to reflect that change. Note that this patch should be applied after Rudolf Marek's w83792d patches.

* [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (5/9)Jean Delvare2005-09-05
| | | | | | | | | | | | | | | Call the ISA chip drivers detection function directly instead of relying on i2c_detect. The net effect is that address lists won't be handled anymore, but they were mostly useless in the ISA case anyway (pc87360, smsc47m1, smsc47b397 had already dropped them). We don't need to handle multiple devices, all we may need is a way to force a given address instead of the original one (some drivers already do: sis5595, via686a, w83627hf), and, for drivers supporting multiple chips, a way to force one given kind. All this may be added later on demand, but I actually don't think there will be much demand. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] I2C: Separate non-i2c hwmon drivers from i2c-core (3/9)Jean Delvare2005-09-05
| | | | | | | | | | | | | | Convert the 10 ISA hardware monitoring drivers (it87, lm78, pc87360, sis5595, smsc47b397, smsc47m1, via686a, w83627hf, w83627ehf, w83781d) to explicitely register with i2c-isa. For hybrid drivers (it87, lm78, w83781d), we now have two separate instances of i2c_driver, one for the I2C interface of the chip, and one for ISA interface. In the long run, the one for ISA will be replaced with a different driver type. At this point, all drivers are working again, except for missing dependencies in Kconfig.
