Merge branch 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging 

Pull hwmon subsystem update from Jean Delvare:
 "There are many improvements to the it87 driver, as well as suspend
  support for the Winbond Super-I/O chips, and a few other fixes."

* 'hwmon-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jdelvare/staging:
  hwmon-vid: Add support for AMD family 11h to 15h processors
  hwmon: (it87) Support PECI for additional chips
  hwmon: (it87) Report thermal sensor type as Intel PECI if appropriate
  hwmon: (it87) Manage device specific features with table
  hwmon: (it87) Replace pwm group macro with direct attribute definitions
  hwmon: (it87) Avoid quoted string splits across lines
  hwmon: (it87) Save fan registers in 2-dimensional array
  hwmon: (it87) Introduce support for tempX_offset sysfs attribute
  hwmon: (it87) Replace macro defining tempX_type sensors with direct definitions
  hwmon: (it87) Save voltage register values in 2-dimensional array
  hwmon: (it87) Save temperature registers in 2-dimensional array
  hwmon: (w83627ehf) Get rid of smatch warnings
  hwmon: (w83627hf) Don't touch nonexistent I2C address registers
  hwmon: (w83627ehf) Add support for suspend
  hwmon: (w83627hf) Add support for suspend

Trip points must be set properly before switching to automatic fan speed

control mode. The driver will perform basic integrity checks before

actually switching to automatic control mode.





Temperature offset attributes

-----------------------------



The driver supports temp[1-3]_offset sysfs attributes to adjust the reported

temperature for thermal diodes or diode-connected thermal transistors.

If a temperature sensor is configured for thermistors, the attribute values

are ignored. If the thermal sensor type is Intel PECI, the temperature offset

must be programmed to the critical CPU temperature.
