* hwmon: (fschmd) Fix a memleak on multiple opens of /dev/watchdogHans de Goede2010-01-251-2/+5
| | | | | | | | | When /dev/watchdog gets opened a second time we return -EBUSY, but we already have got a kref then, so we end up leaking our data struct. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: stable@kernel.org

* lis3: scale output values to mgSamu Onkalo2009-12-152-3/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Report output values as 1/1000 of earth gravity. Output values from lis3 can be read from sysfs position entry and from input device. Input device can be accessed as event device and as joystick device. Joystick device can be in two modes. Meaning of the output values varies from case to case depending on the chip type and configuration (scale). Only joystick interface in JS_CORR_BROKEN mode returned somehow similar output values in different configurations. Joystick device is in that state by default in case of lis3. Position sysfs entry, input event device and raw joystick device have been little bit broken since meaning of the output values has been varied between 12 and 8 bit devices. Applications which relayed on those methods failed if the chip is different than the expected one. This patch converts output values to mean similar thing in different configurations. Both 8 and 12 bit devices reports now same acceleration values. If somebody implements full scale support to the driver, output values will still mean the same. Scaling factor and input device range must be updated in that case. Joystick interface in JS_CORR_BROKEN mode is not touched by this patch. All other interfaces have different scale after this change. For 12 bit device scaling factor is 0.977 which keeps scaled and unscaled values are quite close to each others. For 8 bit device, scaled values are 18 times bigger than unscaled values.

* lis3: selftest supportSamu Onkalo2009-12-152-3/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | Implement selftest feature as specified by chip manufacturer. Control: read selftest sysfs entry Response: "OK x y z" or "FAIL x y z" where x, y, and z are difference between selftest mode and normal mode. Test is passed when values are within acceptance limit values. Acceptance limits are provided via platform data. See chip spesifications for acceptance limits. If limits are not properly set, OK / FAIL decision is meaningless. However, userspace application can still make decision based on the numeric x, y, z values. Selftest is meant for HW diagnostic purposes. It is not meant to be called during normal use of the chip. It may cause false interrupt events. Selftest mode delays polling of the normal results but it doesn't cause wrong values. Chip must be in static state during selftest. Any acceration during the test causes most probably failure.

| | | | | | | | | | | | | | | | | | | | | | Add support for the Analog Devices ADT7490 chip. This chip is largely compatible with the ADT7473 and ADT7475, with additional features. In particular, it has 6 voltage inputs instead of 2.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add support for the ADT7473 to the adt7475 driver, and mark the adt7473 driver for removal. The ADT7473 and ADT7475 chips are almost the same chip and essentially compatible, so there's no point in having separate drivers for them.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support for the Fintek f71889fg to the f71882fg driver, many thanks to Gerd v. Egidy for providing (remote) access to a machine which such an ic. Note that this bit of the patch: - val = SENSORS_LIMIT(val, 0, 255); + + if (data->type == f71889fg) + val = SENSORS_LIMIT(val, -128, 127); + else + val = SENSORS_LIMIT(val, 0, 127); Changes behaviour for already supported models, the new behaviour is correct as the already supported models have bit 7 of the involved registers fixed at 0, so the previous behaviour which allowed setting temp zone limits > 127 was not correct.
