[PATCH 3/3] Adding documentation to sysfs attributes of roccat kone driver

[Stefan Achatz <erazor_de@users.sourceforge.net>]

 This patch adds documentation to sysfs attributes introduced by
 roccat kone mouse driver. The attributes are used by userland
 software already released by me under
 http://sourceforge.net/projects/roccat/

Didn't know if sysfs-driver-hid-roccat-kone or sysfs-driver-usb-roccat-kone
is the right filename, since the sysfs files are in bus/usb path.

I refused to split the What-lines to keep lines under 80 chars.

+What:		/sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/actual_dpi
+Date:		February 2010
+Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
+Description:	It is possible to switch the dpi setting of the mouse with the
+		press of a button.
+		When read, this file returns the raw number of the actual dpi
+		setting of the mouse. This number has to be further processed
+		to receive the real dpi value.
+
+		VALUE DPI
+		1     800
+		2     1200
+		3     1600
+		4     2000
+		5     2400
+		6     3200

+Date:		February 2010
+Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
+Description:	When read, this file returns the raw version number of the
+		firmware stored in the mouse. Using the integer value eases
+		further usage in other programs. To receive the real version
+		number the decimal point has to be shifted 2 positions to the
+		left. E.g. a returned value of 138 means 1.38
+		This file is readonly.

+Date:		February 2010

+Description:	When read, this file returns the driver version.
+		The format of the string is "v<major>.<minor>.<patchlevel>".
+		This filename is used by the userland tools to find the
+		sys-paths of installed kone-mice. Versions of this driver for
+		old kernels replace usbhid instead of generic-usb. The way to
+		scan for this file has been chosen to provide a consistent way
+		for all supported kernel versions.
+		The version number is used to determine the drivers abilities.
+		This file is readonly.

+Date:		February 2010

+Description:	The mouse can store 5 profiles which can be switched by the
+		press of a button. A profile holds informations like button
+		mappings, sensitivity, the colors of the 5 leds and light
+		effects.
+		When read, these files return the respective profile. The
+		returned data is 975 bytes in size.
+		When written, this file lets one write the respective profile
+		data back to the mouse. The data has to be 975 bytes long. The
+		checksum and correct profile number will be set by the driver.
+		The mouse will reject invalid data.

+Description:	When read, this file returns the settings stored in the mouse.
+		The size of the data is 36 bytes and holds information like the
+		startup_profile, tcu state and calibration_data.
+		When written, this file lets write settings back to the mouse.
+		The data has to be 36 bytes long, the checksum will be

+Date:		February 2010
+Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
+Description:	The mouse has a "Tracking Control Unit" which lets the user
+		calibrate the laser power to the mousepad surface.
+		When read, this file returns the current state of the TCU,
+		where 0 means off and 1 means on.
+		Writing 0 in this file will switch the TCU off.
+		Writing 1 in this file will start the calibration which takes
+		around 6 seconds to complete and activates the TCU.

+What:		/sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/weight
+Date:		February 2010

+Description:	The mouse can be equipped with one of four supplied weights
+		ranging from 5 to 20 grams which are recognized by the mouse
+		and its value can be read out. When read, this file returns the
+		raw value returned by the mouse which eases further processing
+		in other software.
+		The values map to the weights as follows:
+
+		VALUE WEIGHT
+		0     none
+		1     5g
+		2     10g
+		3     15g
