-Description
------------
-
-This driver implements support for the Winbond W83627EHF, W83627EHG,
-W83627DHG, W83627DHG-P, W83627UHG, W83667HG, W83667HG-B, W83667HG-I
-(NCT6775F), and NCT6776F super I/O chips. We will refer to them collectively
-as Winbond chips.
-
-The chips implement 3 to 4 temperature sensors (9 for NCT6775F and NCT6776F),
-2 to 5 fan rotation speed sensors, 8 to 10 analog voltage sensors, one VID
-(except for 627UHG), alarms with beep warnings (control unimplemented),
-and some automatic fan regulation strategies (plus manual fan control mode).
-
-The temperature sensor sources on W82677HG-B, NCT6775F, and NCT6776F are
-configurable. temp4 and higher attributes are only reported if its temperature
-source differs from the temperature sources of the already reported temperature
-sensors. The configured source for each of the temperature sensors is provided
-in tempX_label.
-
-Temperatures are measured in degrees Celsius and measurement resolution is 1
-degC for temp1 and and 0.5 degC for temp2 and temp3. For temp4 and higher,
-resolution is 1 degC for W83667HG-B and 0.0 degC for NCT6775F and NCT6776F.
-An alarm is triggered when the temperature gets higher than high limit;
-it stays on until the temperature falls below the hysteresis value.
-Alarms are only supported for temp1, temp2, and temp3.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. Fan
-readings can be divided by a programmable divider (1, 2, 4, 8, 16, 32, 64 or
-128) to give the readings more range or accuracy. The driver sets the most
-suitable fan divisor itself. Some fans might not be present because they
-share pins with other functions.
-
-Voltage sensors (also known as IN sensors) report their values in millivolts.
-An alarm is triggered if the voltage has crossed a programmable minimum
-or maximum limit.
-
-The driver supports automatic fan control mode known as Thermal Cruise.
-In this mode, the chip attempts to keep the measured temperature in a
-predefined temperature range. If the temperature goes out of range, fan
-is driven slower/faster to reach the predefined range again.
-
-The mode works for fan1-fan4. Mapping of temperatures to pwm outputs is as
-follows::
-
-  temp1 -> pwm1
-  temp2 -> pwm2
-  temp3 -> pwm3 (not on 627UHG)
-  prog  -> pwm4 (not on 667HG and 667HG-B; the programmable setting is not
-		 supported by the driver)

-/sys files
-----------
-
-name
-	this is a standard hwmon device entry, it contains the name of
-	the device (see the prefix in the list of supported devices at
-	the top of this file)
-
-pwm[1-4]
-	this file stores PWM duty cycle or DC value (fan speed) in range:
-
-	   0 (stop) to 255 (full)
-
-pwm[1-4]_enable
-	this file controls mode of fan/temperature control:
-
-	* 1 Manual mode, write to pwm file any value 0-255 (full speed)
-	* 2 "Thermal Cruise" mode
-	* 3 "Fan Speed Cruise" mode
-	* 4 "Smart Fan III" mode
-	* 5 "Smart Fan IV" mode
-
-	SmartFan III mode is not supported on NCT6776F.
-
-	SmartFan IV mode is configurable only if it was configured at system
-	startup, and is only supported for W83677HG-B, NCT6775F, and NCT6776F.
-	SmartFan IV operational parameters can not be configured at this time,
-	and the various pwm attributes are not used in SmartFan IV mode.
-	The attributes can be written to, which is useful if you plan to
-	configure the system for a different pwm mode. However, the information
-	returned when reading pwm attributes is unrelated to SmartFan IV
-	operation.
-
-pwm[1-4]_mode
-	controls if output is PWM or DC level
-
-	* 0 DC output (0 - 12v)
-	* 1 PWM output
-
-Thermal Cruise mode
--------------------
-
-If the temperature is in the range defined by:
-
-pwm[1-4]_target
-		   set target temperature, unit millidegree Celsius
-		   (range 0 - 127000)
-pwm[1-4]_tolerance
-		   tolerance, unit millidegree Celsius (range 0 - 15000)
-
-there are no changes to fan speed. Once the temperature leaves the interval,
-fan speed increases (temp is higher) or decreases if lower than desired.
-There are defined steps and times, but not exported by the driver yet.
-
-pwm[1-4]_min_output
-		   minimum fan speed (range 1 - 255), when the temperature
-		   is below defined range.
-pwm[1-4]_stop_time
-		   how many milliseconds [ms] must elapse to switch
-		   corresponding fan off. (when the temperature was below
-		   defined range).
-pwm[1-4]_start_output
-		   minimum fan speed (range 1 - 255) when spinning up
-pwm[1-4]_step_output
-		   rate of fan speed change (1 - 255)
-pwm[1-4]_stop_output
-		   minimum fan speed (range 1 - 255) when spinning down
-pwm[1-4]_max_output
-		   maximum fan speed (range 1 - 255), when the temperature
-		   is above defined range.
-
-Note: last six functions are influenced by other control bits, not yet exported
-      by the driver, so a change might not have any effect.
-
-Implementation Details
-----------------------
-
-Future driver development should bear in mind that the following registers have
-different functions on the 627EHF and the 627DHG. Some registers also have
-different power-on default values, but BIOS should already be loading
-appropriate defaults. Note that bank selection must be performed as is currently
-done in the driver for all register addresses.

-
-			    - "Test Register" for the EHF

-========================= =====================================================
-
-The DHG also supports PECI, where the DHG queries Intel CPU temperatures, and
-the ICH8 southbridge gets that data via PECI from the DHG, so that the
-southbridge drives the fans. And the DHG supports SST, a one-wire serial bus.
-
-The DHG-P has an additional automatic fan speed control mode named Smart Fan
-(TM) III+. This mode is not yet supported by the driver.
