+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the third revision of
+the Abit uGuru chip, found on recent Abit uGuru featuring motherboards.
+
+The 3rd revision of the uGuru chip in reality is a Winbond W83L951G.
+Unfortunatly this doesn't help since the W83L951G is a generic microcontroller

+Kernel driver dme1737
+=====================
+
+Supported chips:
+  * SMSC DME1737 and compatibles (like Asus A8000)
+    Prefix: 'dme1737'
+    Addresses scanned: I2C 0x2c, 0x2d, 0x2e

+
+
+Module Parameters
+-----------------
+
+* force_start: bool	Enables the monitoring of voltage, fan and temp inputs
+			and PWM output control functions. Using this parameter
+			shouldn't be required since the BIOS usually takes care
+			of this.
+
+Note that there is no need to use this parameter if the driver loads without
+complaining. The driver will say so if it is necessary.
+
+
+Description
+-----------
+
+This driver implements support for the hardware monitoring capabilities of the
+SMSC DME1737 and Asus A8000 (which are the same) Super-I/O chips. This chip
+features monitoring of 3 temp sensors temp[1-3] (2 remote diodes and 1
+internal), 7 voltages in[0-6] (6 external and 1 internal) and 6 fan speeds
+fan[1-6]. Additionally, the chip implements 5 PWM outputs pwm[1-3,5-6] for
+controlling fan speeds both manually and automatically.
+
+Fan[3-6] and pwm[3,5-6] are optional features and their availability is
+dependent on the configuration of the chip. The driver will detect which
+features are present during initialization and create the sysfs attributes
+accordingly.
+
+
+Voltage Monitoring
+------------------
+
+The voltage inputs are sampled with 12-bit resolution and have internal
+scaling resistors. The values returned by the driver therefore reflect true
+millivolts and don't need scaling. The voltage inputs are mapped as follows
+(the last column indicates the input ranges):
+
+	in0: +5VTR	(+5V standby)		0V - 6.64V
+	in1: Vccp	(processor core)	0V - 3V
+	in2: VCC	(internal +3.3V)	0V - 4.38V
+	in3: +5V				0V - 6.64V
+	in4: +12V				0V - 16V
+	in5: VTR	(+3.3V standby)		0V - 4.38V
+	in6: Vbat	(+3.0V)			0V - 4.38V
+
+Each voltage input has associated min and max limits which trigger an alarm
+when crossed.
+
+
+Temperature Monitoring
+----------------------
+
+Temperatures are measured with 12-bit resolution and reported in millidegree
+Celsius. The chip also features offsets for all 3 temperature inputs which -
+when programmed - get added to the input readings. The chip does all the
+scaling by itself and the driver therefore reports true temperatures that don't
+need any user-space adjustments. The temperature inputs are mapped as follows
+(the last column indicates the input ranges):
+
+	temp1: Remote diode 1 (3904 type) temperature	-127C - +127C
+	temp2: DME1737 internal temperature		-127C - +127C
+	temp3: Remote diode 2 (3904 type) temperature	-127C - +127C
+
+Each temperature input has associated min and max limits which trigger an alarm
+when crossed. Additionally, each temperature input has a fault attribute that
+returns 1 when a faulty diode or an unconnected input is detected and 0
+otherwise.
+
+
+Fan Monitoring
+--------------
+
+Fan RPMs are measured with 16-bit resolution. The chip provides inputs for 6
+fan tachometers. All 6 inputs have an associated min limit which triggers an
+alarm when crossed. Fan inputs 1-4 provide type attributes that need to be set
+to the number of pulses per fan revolution that the connected tachometer
+generates. Supported values are 1, 2, and 4. Fan inputs 5-6 only support fans
+that generate 2 pulses per revolution. Fan inputs 5-6 also provide a max
+attribute that needs to be set to the maximum attainable RPM (fan at 100% duty-
+cycle) of the input. The chip adjusts the sampling rate based on this value.
+
+
+PWM Output Control
+------------------
+
+This chip features 5 PWM outputs. PWM outputs 1-3 are associated with fan
+inputs 1-3 and PWM outputs 5-6 are associated with fan inputs 5-6. PWM outputs
+1-3 can be configured to operate either in manual or automatic mode by setting
+the appropriate enable attribute accordingly. PWM outputs 5-6 can only operate
+in manual mode, their enable attributes are therefore read-only. When set to
+manual mode, the fan speed is set by writing the duty-cycle value to the
+appropriate PWM attribute. In automatic mode, the PWM attribute returns the
+current duty-cycle as set by the fan controller in the chip. All PWM outputs
+support the setting of the output frequency via the freq attribute.
+
+In automatic mode, the chip supports the setting of the PWM ramp rate which
+defines how fast the PWM output is adjusting to changes of the associated
+temperature input. Associating PWM outputs to temperature inputs is done via
+temperature zones. The chip features 3 zones whose assignments to temperature
+inputs is static and determined during initialization. These assignments can
+be retrieved via the zone[1-3]_auto_channels_temp attributes. Each PWM output
+is assigned to one (or hottest of multiple) temperature zone(s) through the
+pwm[1-3]_auto_channels_zone attributes. Each PWM output has 3 distinct output
+duty-cycles: full, low, and min. Full is internally hard-wired to 255 (100%)
+and low and min can be programmed via pwm[1-3]_auto_point1_pwm and
+pwm[1-3]_auto_pwm_min, respectively. The thermal thresholds of the zones are
+programmed via zone[1-3]_auto_point[1-3]_temp and
+zone[1-3]_auto_point1_temp_hyst:
+
+	pwm[1-3]_auto_point2_pwm	full-speed duty-cycle (255, i.e., 100%)
+	pwm[1-3]_auto_point1_pwm	low-speed duty-cycle
+	pwm[1-3]_auto_pwm_min		min-speed duty-cycle
+
+	zone[1-3]_auto_point3_temp	full-speed temp (all outputs)
+	zone[1-3]_auto_point2_temp	full-speed temp
+	zone[1-3]_auto_point1_temp	low-speed temp
+	zone[1-3]_auto_point1_temp_hyst	min-speed temp
+
+The chip adjusts the output duty-cycle linearly in the range of auto_point1_pwm
+to auto_point2_pwm if the temperature of the associated zone is between
+auto_point1_temp and auto_point2_temp. If the temperature drops below the
+auto_point1_temp_hyst value, the output duty-cycle is set to the auto_pwm_min
+value which only supports two values: 0 or auto_point1_pwm. That means that the
+fan either turns completely off or keeps spinning with the low-speed
+duty-cycle. If any of the temperatures rise above the auto_point3_temp value,
+all PWM outputs are set to 100% duty-cycle.
+
+Following is another representation of how the chip sets the output duty-cycle
+based on the temperature of the associated thermal zone:
+
+			Duty-Cycle	Duty-Cycle
+	Temperature	Rising Temp	Falling Temp
+	-----------	-----------	------------
+	full-speed	full-speed	full-speed
+
+			< linearly adjusted duty-cycle >
+
+	low-speed	low-speed	low-speed
+			min-speed	low-speed
+	min-speed	min-speed	min-speed
+			min-speed	min-speed
+
+
