2014-05-22hwmon: (lm80) Rearrange code to avoid forward declarationsGuenter Roeck1-151/+139
Avoid need for forward declarations by rearranging code. No functional change. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-22hwmon: (lm80) Convert fan display function macros into functionsGuenter Roeck1-34/+41
Convert fan display function macros into functions to reduce code size and improve code readability. Code size reduction is about 200 bytes on x86_64. Signed-off-by: Guenter Roeck <linux@roeck-us.net>

2014-05-22hwmon: (lm80) Normalize all temperature values to 16 bitGuenter Roeck1-18/+14
Normalize all stored temperature values to 16 bit to simplify temperature calculations. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2014-05-22hwmon: (lm80) Simplify TEMP_FROM_REGGuenter Roeck1-14/+3
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>
2014-05-22hwmon: (lm83) Convert to use devm_hwmon_device_register_with_groupsGuenter Roeck1-43/+16

2014-05-22hwmon: (max1619) Fix critical alarm displayGuenter Roeck1-0/+5
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>

2014-05-22hwmon: (emc1403) Add device IDs for EMC1412, EMC1413, and EMC1414Guenter Roeck1-0/+3
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>

2014-05-22hwmon: (emc1403) Relax hysteresis limit write checksGuenter Roeck1-6/+1
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>
2014-05-22hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-onlyGuenter Roeck1-6/+3
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>

2014-05-22hwmon: (lm77) Do not preserve hysteresis when updating critical temp limitGuenter Roeck1-6/+0
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>
