In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This supports parallel port I2C adapters such as the ones made by
Philips or Velleman, Analog Devices evaluation boards, and more.
Basically any adapter using the parallel port as an I2C bus with
no extra chipset is supported by this driver, or could be. Please
read the file Documentation/i2c/busses/i2c-parport.rst for details.

This support is also available as a module. If so, the module
will be called i2c-parport.
