* hwmon: (it87) Preserve configuration register bits on initJean Delvare2012-07-12
| | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It makes sense to label "Digital Thermal Sensor" as "DTS", but unfortunately the string "dts" was already used for "Debug Store", and /proc/cpuinfo is a user space ABI. Therefore, rename this to "dtherm". This conflict went into mainline via the hwmon tree without any x86 maintainer ack, and without any kind of hint in the subject. a4659053 x86/hwmon: fix initialization of coretemp Reported-by: Jean Delvare <khali@linux-fr.org> Link: http://lkml.kernel.org/r/4FE34BCB.5050305@linux.intel.com Cc: Jan Beulich <JBeulich@suse.com> Cc: <stable@vger.kernel.org> v2.6.36..v3.4 Signed-off-by: H.

Specifically, Simplify lookup_comp() to not return an error. Instead, return i_low == i_high if there is an exact match, or if the ohm value is outside the lookup table range. Modify get_temp_mC() to not return an error. Since it only returns an error after lookup_comp() returned an error, this is quite straightforward after above change. Separate ntc_thermistor_read() into a function to read the resistor value (which can return an error), and the call to get_temp_mC() which doesn't. Call the functions directly from ntc_show_temp(). Code was tested using a test program, comparing the result of the old and new versions of get_temp_mC() for resistor values between 0 and 2,000,000 ohm. As a side effect, this patch reduces code size by approximately 400 bytes on x86_64.

* | hwmon: fam15h_power: fix bogus values with current BIOSesAndre Przywara2012-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Newer BKDG[1] versions recommend a different initialization value for the running average range register in the northbridge. This improves the power reading by avoiding counter saturations resulting in bogus values for anything below about 80% of TDP power consumption. Updated BIOSes will have this new value set up from the beginning, but meanwhile we correct this value ourselves. This needs to be done on all northbridges, even on those where the driver itself does not register at. This fixes the driver on all current machines to provide proper values for idle load.

* hwmon: (ad7314) Adds missing spi_dev initializationGraeme Smecher2012-04-03
| | | | | | | | | | | This driver was recently moved from IIO (where it worked) to hwmon (where it doesn't.) This breakage occured because the hwmon version neglected to correctly initialize a reference to spi_dev in its drvdata. The result is a segfault every time the temperature is queried.
