+Kernel driver abituguru
+=======================
+
+Supported chips:
+
+  * Abit uGuru revision 1 & 2 (Hardware Monitor part only)
+
+    Prefix: 'abituguru'
+
+    Addresses scanned: ISA 0x0E0
+
+    Datasheet: Not available, this driver is based on reverse engineering.
+    A "Datasheet" has been written based on the reverse engineering it
+    should be available in the same dir as this file under the name
+    abituguru-datasheet.
+
+    Note:
+	The uGuru is a microcontroller with onboard firmware which programs
+	it to behave as a hwmon IC. There are many different revisions of the
+	firmware and thus effectivly many different revisions of the uGuru.
+	Below is an incomplete list with which revisions are used for which
+	Motherboards:
+
+	- uGuru 1.00    ~ 1.24    (AI7, KV8-MAX3, AN7) [1]_
+	- uGuru 2.0.0.0 ~ 2.0.4.2 (KV8-PRO)
+	- uGuru 2.1.0.0 ~ 2.1.2.8 (AS8, AV8, AA8, AG8, AA8XE, AX8)
+	- uGuru 2.2.0.0 ~ 2.2.0.6 (AA8 Fatal1ty)
+	- uGuru 2.3.0.0 ~ 2.3.0.9 (AN8)
+	- uGuru 3.0.0.0 ~ 3.0.x.x (AW8, AL8, AT8, NI8 SLI, AT8 32X, AN8 32X,
+	  AW9D-MAX) [2]_
+
+.. [1]  For revisions 2 and 3 uGuru's the driver can autodetect the
+	sensortype (Volt or Temp) for bank1 sensors, for revision 1 uGuru's
+	this does not always work. For these uGuru's the autodetection can
+	be overridden with the bank1_types module param. For all 3 known
+	revison 1 motherboards the correct use of this param is:
+	bank1_types=1,1,0,0,0,0,0,2,0,0,0,0,2,0,0,1
+	You may also need to specify the fan_sensors option for these boards
+	fan_sensors=5
+
+.. [2]  There is a separate abituguru3 driver for these motherboards,
+	the abituguru (without the 3 !) driver will not work on these
+	motherboards (and visa versa)!

+
+Module Parameters
+-----------------
+
+* force: bool
+			Force detection. Note this parameter only causes the
+			detection to be skipped, and thus the insmod to
+			succeed. If the uGuru can't be read the actual hwmon
+			driver will not load and thus no hwmon device will get
+			registered.
+* bank1_types: int[]
+			Bank1 sensortype autodetection override:
+
+			  * -1 autodetect (default)
+			  *  0 volt sensor
+			  *  1 temp sensor
+			  *  2 not connected
+* fan_sensors: int
+			Tell the driver how many fan speed sensors there are
+			on your motherboard. Default: 0 (autodetect).
+* pwms: int
+			Tell the driver how many fan speed controls (fan
+			pwms) your motherboard has. Default: 0 (autodetect).
+* verbose: int
+			How verbose should the driver be? (0-3):
+
+			   * 0 normal output
+			   * 1 + verbose error reporting
+			   * 2 + sensors type probing info (default)
+			   * 3 + retryable error reporting
+
+			Default: 2 (the driver is still in the testing phase)
+
+Notice: if you need any of the first three options above please insmod the
+driver with verbose set to 3 and mail me <j.w.r.degoede@hhs.nl> the output of:
+dmesg | grep abituguru
+
+
+Description
+-----------
+
+This driver supports the hardware monitoring features of the first and
+second revision of the Abit uGuru chip found on Abit uGuru featuring
+motherboards (most modern Abit motherboards).
+
+The first and second revision of the uGuru chip in reality is a Winbond
+W83L950D in disguise (despite Abit claiming it is "a new microprocessor
+designed by the ABIT Engineers"). Unfortunately this doesn't help since the
+W83L950D is a generic microcontroller with a custom Abit application running
+on it.
+
+Despite Abit not releasing any information regarding the uGuru, Olle
+Sandberg <ollebull@gmail.com> has managed to reverse engineer the sensor part
+of the uGuru. Without his work this driver would not have been possible.
+
+Known Issues
+------------
+
+The voltage and frequency control parts of the Abit uGuru are not supported.
