* hwmon: (tmp421) Add support for TMP441 and TMP442Guenter Roeck2014-08-042-5/+18
| | | | | | | TMP441 and TMP442 are compatible to TMP421 and TMP422. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Jean Delvare <jdelvare@suse.de>
* hwmon: (tmp421) Strengthen detect functionGuenter Roeck2014-08-041-0/+14
| | | | | | | | | Not all supported chips support the entire I2C address range. Only accept specific chips at the addresses supported by that chip. Check for invalid values in conversion rate and status registers. Signed-off-by: Guenter Roeck <linux@roeck-us.net> Reviewed-by: Jean Delvare <jdelvare@suse.de>

* hwmon: (lm77) Prevent overflow problem when writing large limitsAxel Lin2014-07-311-5/+6
| | | | | | | | | | | | | | | | On platforms with sizeof(int) < sizeof(long), writing a temperature limit larger than MAXINT will result in unpredictable limit values written to the chip. Clamp the input values to the supported limits first to fix the problem. For set_temp_hyst: As Guenter pointed out that the temperature is read as unsigned and stored in an unsigned long. This is wrong; nothing in the datasheet suggests that the value (the absolute temperature) must be positive. So change it to signed.
