2013-05-11hwmon: (nct6775) Do not create non-existing attributesGuenter Roeck
Overtemperature and hysteresis registers only exist for primary temperature registers, not for alternates, so do not assign those registers when initializing alternates. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-21hwmon: (nct6775) Fix coding style problemsGuenter Roeck
Add space around binary operators (CodingStyle, chapter 3.1). Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-21hwmon: (nct6775) Constify stringsGuenter Roeck
nct6775_sio_names should be a constant pointer to an array of constant strings. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-13hwmon: (nct6775) Use ARRAY_SIZE for loops where possibleGuenter Roeck
This ensures that the loop iterations are correct even if/when the number of elements in an array changes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Enable both AUXTIN and VIN3 on NCT6776Guenter Roeck
Per datasheet, VIN3 and AUXTIN share the same external pin. However, there is no clean way to detect this condition. Furthermore, both are reported by the BIOS on Supermicro C7H61. It may thus be possible that chip revisions exist where both attributes are supported at the same time. Better play safe and report both. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Expand scope of supported chipsGuenter Roeck
NCT6775, NCT6776, and NCT6779 have a number of variants with the same chip ID but different chip labels. Add text "or compatible" to the message displayed when the driver is loaded and rephrase the Kconfig entry to reflect that it also supports compatible chips. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Drop read/write lockGuenter Roeck
The read/write lock is acquired for each read/write operation from/to the chip. This occurs either during initialization, when it is not needed, or during updates, when the update_lock is held as well, and it is not needed either. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Only report VID if supported and enabledGuenter Roeck
VID is not always enabled (NCT6775, NCT6776) or supported (NCT6779). Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Detect and report additional temperature sourcesGuenter Roeck
Scan all temperature sources used for fan control and report if additional monitoring registers are available. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for weighted fan controlGuenter Roeck
The NCT677X series support weighted fan control. In this mode, a secondary temperature source is used in addition to the primary temperature source to control fan speed. Add support for this feature. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for automatic fan controlGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for pwm, pwm_mode, and pwm_enableGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add power management supportGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for fan debounce module parameterGuenter Roeck
If set, fan debounce is enabled when loading the driver. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for fanX_pulses sysfs attributeGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for fan speed attributesGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add support for temperature sensorsGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: (nct6775) Add case open detectionGuenter Roeck
Signed-off-by: Guenter Roeck <linux@roeck-us.net>
2013-04-07hwmon: Driver for Nuvoton NCT6775F, NCT6776F, and NCT6779DGuenter Roeck
This driver will replace the w83627ehf driver for NCT6775F and NCT6776F, and provides support for NCT6779D. This patch provides support for voltage monitor attributes. Signed-off-by: Guenter Roeck <linux@roeck-us.net>
