* hwmon/sch56xx: Depend on watchdog for watchdog core functionsHans de Goede2012-05-30
| | | | | | | | | Since the watchdog code in sch56xx-common now uses the watchdog core, the Kconfig entires for the sch5627 and sch5636 should depend on WATCHDOG being set. Also select the watchdog core when we select one of the drivers. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: sch56xx-common: set correct bits in register()Dan Carpenter2012-05-30
| | | | | | | | | | WDOG_NO_WAY_OUT (3) and WDOG_ACTIVE (0) are the bit numbers, not a mask. So "data->wddev.status |= WDOG_ACTIVE;" was intended to set bit zero but it is a no-op.

* watchdog: sch56xx-common: Add proper ref-counting of watchdog dataHans de Goede2012-05-30
| | | | | | | | This fixes referencing free-ed memory in the corner case where /dev/watchdog is open when the platform driver gets unbound from the platform device. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Wim Van Sebroeck <wim@iguana.be>
* watchdog: sch56xx: Remove unnecessary checks for register changesHans de Goede2012-05-30
| | | | | | | | | | Since the watchdog core keeps track of the watchdog's active state, start/stop will never get called when no changes are necessary. So we can remove the check for the output_enable register changing before writing it (which is an expensive operation).

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: (k10temp) Add support for AMD Trinity CPUsAndre Przywara2012-04-01
| | | | | | | | | | | | The on-chip northbridge's temperature sensor of the upcoming AMD Trinity CPUs works the same as for the previous CPUs. Since it has a different PCI-ID, we just add the new one to the list supported by k10temp. This allows to use the k10temp driver on those CPUs.

* hwmon: (w83627ehf) mark const init data with __initconst instead of __initdataUwe Kleine-König2012-04-01
| | | | | | | | | | | | | | | | | As long as there is no other non-const variable marked __initdata in the same compilation unit it doesn't hurt. If there were one however compilation would fail with error: $variablename causes a section type conflict because a section containing const variables is marked read only and so cannot contain non-const variables.

* hwmon: (adm1031) Fix compiler warningGuenter Roeck2012-04-01
