* hwmon: (w83l786ng) Report correct minimum fan speedAxel Lin2014-06-251-1/+1
| | | | | | | | | Current code is buggy, it shows the current fan speed as minimum fan speed. Fix up show_fan_reg macro to correctly report fan and fan_min speed. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Kevin Lo <kevlo@kevlo.org> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (lm85) Drop generic detectionJean Delvare2014-06-121-23/+10
| | | | | | | | | | Generic detection leads to too many false positives, so drop it. FWIW sensors-detect does not have such generic detection. If the user wants to force the driver to bind to a not yet supported chip, he/she can still do so using sysfs attribute new_device.

* hwmon: (ina2xx) Cast to s16 on shunt and current regsFabio Baltieri2014-06-121-3/+4
| | | | | | | | | | | | | | | All devices supported by ina2xx are bidirectional and report the measured shunt voltage and power values as a signed 16 bit, but the current driver implementation caches all registers as u16, leading to an incorrect sign extension when reporting to userspace in ina2xx_get_value(). This patch fixes the problem by casting the signed registers to s16. Tested on an INA219.

| | | | | | | | | | | | | | | | | | | | | | | | | | TEMP_FROM_REG gets 12 bits of temperature data in the upper 12 bit of a signed 16 bit parameter, with the integer part (including sign) in the upper 8 bit and the remainder in bit 4..7. The lower 4 bit of the 16 bit data is always 0. We can use that information to convert the temperature directly into display data (1/1000th of degree C). Note that the stored temperature data is not shifted right as the comment claimed, so remove that misleading comment. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
