hwmon: (nct6775) Remove num_attr_groups from struct nct6775_data

2014-08-04T14:01:40+00:00

num_attr_groups is only used in nct6775_probe(), make it to be local variable.

hwmon: (nct6775) Update module description and Kconfig for NCT6106D and NCT6791D

2014-08-04T14:01:40+00:00

This driver also supports NCT6106D and NCT6791D, thus update module description
and Kconfig accordingly.

hwmon: (nct6775) Fix probe unwind paths to properly unregister platform devices

2014-05-24T15:30:29+00:00

Call platform_device_unregister() rather than platform_device_put() to
unregister successfully registered platform devices.

hwmon: (nct6775) Re-enable logical device mapping for NCT6791 during resume

2014-01-15T05:36:53+00:00

After a suspend/resume cycle, the NCT6791 is back to its original BIOS
programming. In this state, HWMON IO access may be locked.
Re-enable it during resume.

hwmon: (nct6775) NCT6791 supports weight control only for CPUFAN

2013-11-18T22:08:05+00:00

Unlike other chips supported by this driver, the NCT6791 only has a single
set of registers to configure weighted fan control. Enable it only for the
single channel supporting it.

hwmon: (nct6775) Monitor additional temperature registers

2013-11-18T22:08:05+00:00

The number of SMIOVT registers on NCT6779 and NCT6791 is limited to 2.
As result, the driver may not report some of the temperatures used
for fan control. This can result in some of the pwmX_temp_sel or
pwm2_weight_temp_sel attributes to wrongly return 0.
Fortunately, the chip has registers to monitor those temperatures.
Add them to the list of temperatures to report.
