The platform is removed, so there are no users of this driver.

- * I2C adapter for IXP2000 systems using GPIOs for I2C bus
- *
- * Author: Deepak Saxena <dsaxena@xxxxxxxxxxx>

- * 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.
