2015-08-09hwmon: (nct7802) add temperature sensor type attributeConstantine Shulyupin1-12/+60
Sensor type: 3 diode (current mode), MD=1 4 thermistor, MD=2 Reference: Nuvoton Hardware Monitoring IC NCT7802Y 7.2.32 Mode Selection Register Location : Index 22h Signed-off-by: Constantine Shulyupin <const@MakeLinux.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-07-30hwmon: (nct7802) Fix integer overflow seen when writing voltage limitsGuenter Roeck1-1/+1
Writing a large value into a voltage limit attribute can result in an overflow due to an auto-conversion from unsigned long to unsigned int.

Excerpt from datasheet: 7.2.32 Mode Selection Register RTD3_MD : 00=Closed , 01=Reserved , 10=Thermistor mode , 11=Voltage sense Show temp3 only in Thermistor mode Cc: stable@vger.kernel.org # v3.19+ Signed-off-by: Constantine Shulyupin <const@MakeLinux.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2015-01-26hwmon: (nct7802) Constify struct regmap_configKrzysztof Kozlowski1-1/+1
The regmap_config struct may be const because it is not modified by the driver and regmap_init() accepts pointer to const. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
