Description
-----------
-The ADT7410 is a temperature sensor with rated temperature range of -55°C to
-+150°C. It has a high accuracy of +/-0.5°C and can be operated at a resolution
-of 13 bits (0.0625°C) or 16 bits (0.0078°C). The sensor provides an INT pin to
-indicate that a minimum or maximum temperature set point has been exceeded, as
-well as a critical temperature (CT) pin to indicate that the critical
-temperature set point has been exceeded. Both pins can be set up with a common
-hysteresis of 0°C - 15°C and a fault queue, ranging from 1 to 4 events. Both
-pins can individually set to be active-low or active-high, while the whole
-device can either run in comparator mode or interrupt mode. The ADT7410
-supports continous temperature sampling, as well as sampling one temperature
-value per second or even justget one sample on demand for power saving.
-Besides, it can completely power down its ADC, if power management is
-required.
-
-The ADT7420 is register compatible, the only differences being the package,
-a slightly narrower operating temperature range (-40°C to +150°C), and a
-better accuracy (0.25°C instead of 0.50°C.)

+
+Description
+-----------
+
+LM95234 is an 11-bit digital temperature sensor with a 2-wire System Management
+Bus (SMBus) interface and TrueTherm technology that can very accurately monitor
+the temperature of four remote diodes as well as its own temperature.
+The four remote diodes can be external devices such as microprocessors,
+graphics processors or diode-connected 2N3904s. The LM95234's TruTherm
+beta compensation technology allows sensing of 90 nm or 65 nm process
+thermal diodes accurately.
+
+All temperature values are given in millidegrees Celsius. Temperature
+is provided within a range of -127 to +255 degrees (+127.875 degrees for
+the internal sensor). Resolution depends on temperature input and range.
+
+Each sensor has its own maximum limit, but the hysteresis is common to all
+channels. The hysteresis is configurable with the tem1_max_hyst attribute and
+affects the hysteresis on all channels. The first two external sensors also
+have a critical limit.
+
+The lm95234 driver can change its update interval to a fixed set of values.
+It will round up to the next selectable interval. See the datasheet for exact
+values. Reading sensor values more often will do no harm, but will return
+'old' values.

+
+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[1-5] - this file stores PWM duty cycle or DC value (fan speed) in range:
+ 0 (lowest speed) to 255 (full)
+
+pwm[1-5]_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[1-5]_mode - controls if output is PWM or DC level
+ * 0 DC output
+ * 1 PWM output
+
+Common fan control attributes
+-----------------------------
+
+pwm[1-5]_temp_sel Temperature source. Value is temperature sensor index.
+ For example, select '1' for temp1_input.
+pwm[1-5]_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[1-5]_weight_duty_step
+ Duty step size.
+pwm[1-5]_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[1-5]_weight_temp_step_base
+ Temperature at which secondary temperature control kicks
+ in.
+pwm[1-5]_weight_temp_step_tol
+ Temperature step tolerance.
+
+Thermal Cruise mode (2)
+-----------------------
+
+If the temperature is in the range defined by:
+
+pwm[1-5]_target_temp Target temperature, unit millidegree Celsius
+ (range 0 - 127000)
+pwm[1-5]_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[1-5]_start fan pwm start value (range 1 - 255), to start fan
+ when the temperature is above defined range.
+pwm[1-5]_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[1-5]_step_up_time milliseconds before fan speed is increased
+pwm[1-5]_step_down_time milliseconds before fan speed is decreased
+pwm[1-5]_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[1-5]_target Target fan speed
+fan[1-5]_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[1-5]_auto_point[1-7]_pwm
+ pwm value to be set if temperature reaches matching
+ temperature range.
+pwm[1-5]_auto_point[1-7]_temp
+ Temperature over which the matching pwm is enabled.
+pwm[1-5]_temp_tolerance
+ Temperature tolerance, unit millidegree Celsius
+pwm[1-5]_crit_temp_tolerance
+ Temperature tolerance for critical temperature,
+ unit millidegree Celsius
+
+pwm[1-5]_step_up_time milliseconds before fan speed is increased
+pwm[1-5]_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.
The humidity calibration coefficients are programmed into an OTP memory on the
chip. These coefficients are used to internally calibrate the signals from the
sensors. Disabling the reload of those coefficients allows saving 10ms for each
-measurement and decrease power consumption, while loosing on precision.
