* hwmon: (w83781d) Request I/O ports individually for probingJean Delvare2010-02-051-13/+13
| | | | | | | | | | | | | | | | | Different motherboards have different PNP declarations for W83781D/W83782D chips. Some declare the whole range of I/O ports (8 ports), some declare only the useful ports (2 ports at offset 5) and some declare fancy ranges, for example 4 ports at offset 4. To properly handle all cases, request all ports individually for probing. After we have determined that we really have a W83781D or W83782D chip, the useful port range will be requested again, as a single block. I did not see a board which needs this yet, but I know of one for lm78 driver and I'd like to keep the logic of these two drivers in sync.

* hwmon: (lm78) Request I/O ports individually for probingJean Delvare2010-02-051-13/+12
| | | | | | | | | | | | | | | Different motherboards have different PNP declarations for LM78/LM79 chips.

* hwmon: (adt7462) Wrong ADT7462_VOLT_COUNTRay Copeland2010-02-051-1/+1
| | | | | | | | | | | | | | The #define ADT7462_VOLT_COUNT is wrong, it should be 13 not 12. All the for loops that use this as a limit count are of the typical form, "for (n = 0; n < ADT7462_VOLT_COUNT; n++)", so to loop through all voltages w/o missing the last one it is necessary for the count to be one greater than it is. (Specifically, you will miss the +1.5V 3GPIO input with count = 12 vs. 13.) Signed-off-by: Ray Copeland <ray.copeland@aprius.com> Acked-by: "Darrick J.

* 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.

| * hwmon: (adt7475) Voltage attenuators can be bypassedJean Delvare2009-12-091-6/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | It is possible to bypass the voltage attenuators on the +2.5V, Vccp, +5V and +12V voltage monitoring inputs. This is useful to connect other voltage channels than the ones the monitoring chip was originally designed for. When this feature is enabled, we must not include the scaling factors in our computations.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The TACH4 pin can be used for other functions, so fan4 may not always be available. Likewise, the PWM2 pin can be used for ALERT output, in which case pwm2 is not available For the ADT7490, the +2.5 Vin pin may also be used for other functions, in which case in0 is not available.

| * hwmon: (adt7475) Move sysfs files removal to a separate functionJean Delvare2009-12-091-6/+10
| | | | | | | | | | | | | | | | | | | | | | | | Move sysfs files removal to a separate function. The code is common to the device probing error path and the standard device removal path. As it will grow with future driver development, this avoids code duplication.

| | | | | | | | | | | | | | | | | | | | | | 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.
