-Description
------------
-
-This driver implements support for the Nuvoton NCT6775F, NCT6776F, and NCT6779D
-and compatible super I/O chips.
-
-The chips support up to 25 temperature monitoring sources. Up to 6 of those are
-direct temperature sensor inputs, the others are special sources such as PECI,
-PCH, and SMBUS. Depending on the chip type, 2 to 6 of the temperature sources
-can be monitored and compared against minimum, maximum, and critical
-temperatures. The driver reports up to 10 of the temperatures to the user.
-There are 4 to 5 fan rotation speed sensors, 8 to 15 analog voltage sensors,
-one VID, alarms with beep warnings (control unimplemented), and some automatic
-fan regulation strategies (plus manual fan control mode).
-
-The temperature sensor sources on all chips are configurable. The configured
-source for each of the temperature sensors is provided in tempX_label.
-
-Temperatures are measured in degrees Celsius and measurement resolution is
-either 1 degC or 0.5 degC, depending on the temperature source and
-configuration. An alarm is triggered when the temperature gets higher than
-the high limit; it stays on until the temperature falls below the hysteresis
-value. Alarms are only supported for temp1 to temp6, depending on the chip type.
-
-Fan rotation speeds are reported in RPM (rotations per minute). An alarm is
-triggered if the rotation speed has dropped below a programmable limit. On
-NCT6775F, 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 other chips
-do not have a fan speed divider. The driver sets the most suitable fan divisor
-itself; specifically, it increases the divider value each time a fan speed
-reading returns an invalid value, and it reduces it if the fan speed reading
-is lower than optimal. 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-fan5.

-sysfs attributes
-----------------
-
-pwm[1-7]
-    - this file stores PWM duty cycle or DC value (fan speed) in range:
-
-	   0 (lowest speed) to 255 (full)
-
-pwm[1-7]_enable
-    - this file controls mode of fan/temperature control:
-
-	* 0 Fan control disabled (fans set to maximum speed)
-	* 1 Manual mode, write to pwm[0-5] any value 0-255
-	* 2 "Thermal Cruise" mode
-	* 3 "Fan Speed Cruise" mode
-	* 4 "Smart Fan III" mode (NCT6775F only)
-	* 5 "Smart Fan IV" mode
-
-pwm[1-7]_mode
-    - controls if output is PWM or DC level
-
-	* 0 DC output
-	* 1 PWM output
-
-Common fan control attributes
------------------------------
-
-pwm[1-7]_temp_sel
-			Temperature source. Value is temperature sensor index.
-			For example, select '1' for temp1_input.
-
-pwm[1-7]_weight_temp_sel
-			Secondary temperature source. Value is temperature
-			sensor index. For example, select '1' for temp1_input.
-			Set to 0 to disable secondary temperature control.
-
-If secondary temperature functionality is enabled, it is controlled with the
-following attributes.
-
-pwm[1-7]_weight_duty_step
-			Duty step size.
-
-pwm[1-7]_weight_temp_step
-			Temperature step size. With each step over
-			temp_step_base, the value of weight_duty_step is added
-			to the current pwm value.
-
-pwm[1-7]_weight_temp_step_base
-			Temperature at which secondary temperature control kicks
-			in.
-
-pwm[1-7]_weight_temp_step_tol
-			Temperature step tolerance.
-
-Thermal Cruise mode (2)
------------------------
-
-If the temperature is in the range defined by:
-
-pwm[1-7]_target_temp
-			Target temperature, unit millidegree Celsius
-			(range 0 - 127000)
-
-pwm[1-7]_temp_tolerance
-			Target temperature tolerance, unit millidegree Celsius
-
-There are no changes to fan speed. Once the temperature leaves the interval, fan
-speed increases (if temperature is higher that desired) or decreases (if
-temperature is lower than desired), using the following limits and time
-intervals.
-
-pwm[1-7]_start
-			fan pwm start value (range 1 - 255), to start fan
-			when the temperature is above defined range.
-
-pwm[1-7]_floor
-			lowest fan pwm (range 0 - 255) if temperature is below
-			the defined range. If set to 0, the fan is expected to
-			stop if the temperature is below the defined range.
-
-pwm[1-7]_step_up_time
-			milliseconds before fan speed is increased
-
-pwm[1-7]_step_down_time
-			milliseconds before fan speed is decreased
-
-pwm[1-7]_stop_time
-			how many milliseconds must elapse to switch
-			corresponding fan off (when the temperature was below
-			defined range).
-
-Speed Cruise mode (3)
----------------------
-
-This modes tries to keep the fan speed constant.
-
-fan[1-7]_target
-			Target fan speed
-
-fan[1-7]_tolerance
-			Target speed tolerance
-
-
-Untested; use at your own risk.
-
-Smart Fan IV mode (5)
----------------------
-
-This mode offers multiple slopes to control the fan speed. The slopes can be
-controlled by setting the pwm and temperature attributes. When the temperature
-rises, the chip will calculate the DC/PWM output based on the current slope.
-There are up to seven data points depending on the chip type. Subsequent data
-points should be set to higher temperatures and higher pwm values to achieve
-higher fan speeds with increasing temperature. The last data point reflects
-critical temperature mode, in which the fans should run at full speed.
-
-pwm[1-7]_auto_point[1-7]_pwm
-			pwm value to be set if temperature reaches matching
-			temperature range.
-
-pwm[1-7]_auto_point[1-7]_temp
-			Temperature over which the matching pwm is enabled.
-
-pwm[1-7]_temp_tolerance
-			Temperature tolerance, unit millidegree Celsius
-
-pwm[1-7]_crit_temp_tolerance
-			Temperature tolerance for critical temperature,
-			unit millidegree Celsius
-
-pwm[1-7]_step_up_time
-			milliseconds before fan speed is increased
-
-pwm[1-7]_step_down_time
-			milliseconds before fan speed is decreased
-
-Usage Notes
------------
-
-On various ASUS boards with NCT6776F, it appears that CPUTIN is not really
-connected to anything and floats, or that it is connected to some non-standard
-temperature measurement device. As a result, the temperature reported on CPUTIN
-will not reflect a usable value. It often reports unreasonably high
-temperatures, and in some cases the reported temperature declines if the actual
-temperature increases (similar to the raw PECI temperature value - see PECI
-specification for details). CPUTIN should therefore be be ignored on ASUS
-boards. The CPU temperature on ASUS boards is reported from PECI 0.
