hwmon: (ntc_thermistor) Use the manufacturer name properly

2014-06-25T14:09:13+00:00

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.

Pull hwmon updates from Guenter Roeck:
 "New driver for NCT6683D

  New chip support to existing drivers:
   - add support for STTS2004 and AT30TSE004 to jc42 driver
   - add support for EMC1402/EMC1412/EMC1422 to emc1403 driver

  Other notable changes:
   - document hwmon kernel API
   - convert jc42, lm70, lm75, lm77, lm83, lm92, max1619, tmp421, and
     tmp102 drivers to use new hwmon API functions
   - replace function macros in lm80, lm92, and jc42 drivers with real
     code
   - convert emc1403 driver to use regmap, add support for additional
     attributes, and add device IDs for EMC1412, EMC1413, and EMC1414
   - various additional cleanup and minor bug fixes in several drivers"

hwmon: Document temp[1-*]_min_hyst sysfs attribute

2014-05-25T15:23:07+00:00

The temp[1-*]_min_hyst sysfs attribute is already implemented by 3
hwmon drivers (adt7x10, lm77 and lm92) but was missing from the
standard interface.

Also add temp[1-*]_lcrit_hyst for consistency, even though no driver
implement that one for the time being.

hwmon: (emc1403) Make all hyst attributes except for temp1_crit_hyst read-only

2014-05-21T23:02:24+00:00

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.

hwmon: (lm77) Do not preserve hysteresis when updating critical temp limit

2014-05-21T23:02:20+00:00

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.
