* hwmon: (gpio-fan) Change name used in hwmon_device_register_with_groupsJulien D'Ascenzio2014-06-251-1/+1
| | | | | | | | | | Since commit 648cd48c9e566f53c5df30d79857e0937ae13b09 The hwmon name attributes must not include '-' so the name must be rename from gpio-fan to gpio_fan Signed-off-by: Julien D'Ascenzio <jdascenzio@yahoo.fr> Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

* hwmon: (ntc_thermistor) Use the manufacturer name properlyNaveen Krishna Chatradhi2014-06-252-3/+16
| | | | | | | | | | | | | | | | | Murata Manufacturing Co., Ltd is the vendor for NTC (Negative Temperature coefficient) based Thermistors. But, the driver extensively uses "NTC" as the vendor name. This patch corrects the vendor name also updates the compatibility strings according to the vendor-prefix.txt Note: Drivers continue to support the previous compatible strings but further addition of these compatible strings in device tree is deprecated.

* 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>
