+Parallel Port Adapters
+----------------------
+If you are installing parallel port adapters it means you are probably messing 
+around with wires and IC's and the like. If you have purchased a card that 
+provides an external i2c/smbus this will require combined algorithm and 
+adapter code in a single module.
+If you are doing it yourself by using the parallel port there 
+are basically 2 options.
+
+1) Using the parallel port and using the i2c-pport adapter module and the 
+i2c-algo-bit algorithm module together to enable you to wire up your parallel 
+port to act as an i2c/smbus. This provides a bus that will enable most 
+sensors to work but doesn't support the entire i2c/smbus capability.
+
+2) Using the parallel port to interface to a Philips PCF8584 parallel to i2c 
+adapter chip. You will need to build a bit of a circuit to do this. This 
+configuration needs the i2c-pcf-epp adapter module and the i2c-algo-pcf 
+algorithm module. This support almost all of the i2c/smbus capabilities.
+
+
+i2c-pport Documentation
+-----------------------
+This is a primitive parallel port driver for the i2c bus, which exploits 
+features of modern bidirectional parallel ports. 
+
+Bidirectional ports have particular bits connected in following way:
+   
+                        |
+            /-----|     R
+         --o|     |-----|
+      read  \-----|     /------- Out pin
+                      |/
+                   - -|\
+                write   V
+                        |
+                       ---  
+
+
+It means when output is set to 1 we can read the port. Therefore 
+we can use 2 pins of parallel port as SDA and SCL for i2c bus. It 
+is not necessary to add any external - additional parts, we can 
+read and write the same port simultaneously.
+	I only use register base+2 so it is possible to use all 
+8 data bits of parallel port for other applications (I have 
+connected EEPROM and LCD display). I do not use bit Enable Bi-directional
+ Port. The only disadvantage is we can only support 5V chips.
+
+Layout:
+
+Cannon 25 pin
+
+SDA - connect to pin 14 (Auto Linefeed)
+SCL - connect to pin 16 (Initialize Printer)
+GND - connect to pin 18-25
++5V - use external supply (I use 5V from 3.5" floppy connector)
+      
+no pullups  requied
+
+Module parameters:
+
+base = 0xXXX
+XXX - 278 or 378
+
+That's all.

-Module usage count
-==================
-
-If your driver can also be compiled as a module, there are moments at 
-which the module can not be removed from memory. For example, when you
-are doing a lengthy transaction, or when you create a /proc directory,
-and some process has entered that directory (this last case is the
-main reason why these call-backs were introduced).
-
-To increase or decrease the module usage count, you can use the
-MOD_{INC,DEC}_USE_COUNT macros. They must be called from the module
-which needs to get its usage count changed; that is why each driver
-module has to implement its own callback.

-  void i2c_dec_use_client(struct i2c_client *);
