- * I2C adapter for IXP2000 systems using GPIOs for I2C bus
- *
- * Author: Deepak Saxena <dsaxena@plexity.net>
- * Based on IXDP2400 code by: Naeem M. Afzal <naeem.m.afzal@intel.com>
- * Made generic by: Jeff Daly <jeffrey.daly@intel.com>

- * From Jeff Daly:
- *
- * I2C adapter driver for Intel IXDP2xxx platforms. This should work for any
- * IXP2000 platform if it uses the HW GPIO in the same manner.  Basically, 
- * SDA and SCL GPIOs have external pullups.  Setting the respective GPIO to 
- * an input will make the signal a '1' via the pullup.  Setting them to 
- * outputs will pull them down. 
- *
- * The GPIOs are open drain signals and are used as configuration strap inputs
- * during power-up so there's generally a buffer on the board that needs to be 
- * 'enabled' to drive the GPIOs.
