2014-05-21hwmon: (max1619) Rearrange code to avoid forward declarationsGuenter Roeck
Forward declarations are unnecessary and easy to avoid, so rearrange code and drop them. No functional change. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (max1619) Drop FSF addressGuenter Roeck
The FSF address may chance over time, so drop it. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (max1619) Fix critical alarm displayGuenter Roeck
The overtemperature status bit, which is used to display critical alarm status, matches the output of the OVERT signal 1:1. If that signal is active-low, the bit will read 1 if there is no alarm. It is therefore necessary to reverse the bit in this case. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (jc42) Add support for STTS2004 and AT30TSE004Guenter Roeck
Also fix links to datasheets for other supported sensors from ST Microelectronics, and add links to several Atmel datasheets. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (jc42) Convert function macros into functionsGuenter Roeck
Convert function macros into functions to make the code easier to read and reduce code size. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-05-21hwmon: (emc1403) Add device IDs for EMC1412, EMC1413, and EMC1414Guenter Roeck
EMC1412, EMC1413, and EMC1414 are fully compatible to EMC1402, EMC1403, and EMC1404, and even report the same chip ID. Add to device ID table to enable instantiation with correct chip names. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (emc1403) Add support for min_hyst attributesGuenter Roeck
The hysteresis value applies to all limits, so add support for tempX_min_hyst. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (emc1403) Add support for max_hyst attributesGuenter Roeck

2014-05-21hwmon: (emc1403) Relax hysteresis limit write checksGuenter Roeck
Writing the hysteresis limit returned -ERANGE if the written hysteresis was too high or too low. Relax error check and adjust the hysteresis value to its valid range. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-21hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-onlyGuenter Roeck
All chips in this chip series only support a single hysteresis value. Having multiple writable hysteresis attributes is therefore confusing, since a single write affects all hysteresis temperatures. Make all but one (temp1_crit_hyst) read-only. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-05-21hwmon: (lm77) Do not preserve hysteresis when updating critical temp limitGuenter Roeck
Updating the hysteresis value when updating the critical temperature limit was following the rule of 'least surprise'. However, it had the undesirable side effect of changing the hysteresis for all other attributes, which defeats the purpose of least surprise. In addition, it could result in invalid hysteresis values if the resulting hysteresis was too large. In such cases the resulting hysteresis ended up changed anyway, which again defeats the purpose. So drop that code and document the new behavior. Reviewed-by: Jean Delvare <jdelvare@suse.de> Signed-off-by: Guenter Roeck <linux@roeck-us.net>
