hwmon: (it87) Preserve configuration register bits on init

2012-07-25T03:11:17Z

commit 41002f8dd5938d5ad1d008ce5bfdbfe47fa7b4e8 upstream. We were accidentally losing one bit in the configuration register on device initialization. It was reported to freeze one specific system right away. Properly preserve all bits we don't explicitly want to change in order to prevent that.

hwmon: (it87) Add chassis intrusion detection support

2011-07-25T19:46:10Z

Add chassis intrusion detection support for all supported devices, using the standard interface. Signed-off-by: Jean Delvare

hwmon: (it87) Fix label group removal

2011-07-17T16:39:19Z

A copy-and-paste error caused it87_attributes_vid to be referenced where it87_attributes_label should be. Thankfully the group is only used for attribute removal, not attribute creation, so the effects of this bug are limited, but let's fix it still.

hwmon: (it87) Use request_muxed_region

2011-05-25T18:43:33Z

Serialize access to the hardware by using "request_muxed_region" macro defined by Alan Cox. Call to this macro will hold off the requestor if the resource is currently busy. "superio_enter" will return an error if call to "request_muxed_region" fails. Rest of the code change is to ripple an error return from superio_enter to the top level.

hwmon: (it87) Fix manual fan speed control on IT8721F

2010-12-08T15:27:22Z

The manual fan speed control logic of the IT8721F is much different from what older devices had. Update the code to properly support that. Signed-off-by: Jean Delvare Acked-by: Guenter Roeck

hwmon: (it87) Add support for the IT8721F/IT8758E

2010-10-28T18:31:51Z

Add support for the IT8721F/IT8758E. These new chips differ from the older IT87xxF chips in the following ways: * ADC LSB is 12 mV instead of 16 mV. * PWM values are 8-bit instead of 7-bit. There are other minor changes we don't have to care about in the driver. Another change is that we will handle internal voltage scaling in the driver instead of delegating the work to user-space.

hwmon: (it87) Move conversion functions

2010-10-28T18:31:51Z

Move conversion functions until after structure defintions. This is needed for future changes which make use of the structures in the conversion funtcions. Signed-off-by: Jean Delvare

hwmon: (it87) Export labels for internal sensors

2010-08-14T19:08:50Z

Some voltage sensors can be wired internally to the IT87xxF chip's own power supply channels. In that case, we can inform user-space that the wiring is known by exporting proper labels for these sensors. Signed-off-by: Jean Delvare

hwmon: (it87) Fix in7 on IT8720F

2010-07-09T14:22:48Z

The IT8720F has no VIN7 pin, so VCCH should always be routed internally to VIN7 with an internal divider. Curiously, there still is a configuration bit to control this, which means it can be set incorrectly. And even more curiously, many boards out there are improperly configured, even though the IT8720F datasheet claims that the internal routing of VCCH to VIN7 is the default setting. So we force the internal routing in this case. It turns out that all boards with the wrong setting are from Gigabyte, so I suspect a BIOS bug. But it's easy enough to workaround in the driver, so let's do it. Signed-off-by: Jean Delvare Cc: Jean-Marc Spaggiari Cc: stable@kernel.org
