762 This supports parallel port I2C adapters such as the ones made by
763 Philips or Velleman, Analog Devices evaluation boards, and more.
764 Basically any adapter using the parallel port as an I2C bus with
765 no extra chipset is supported by this driver, or could be.
766
767 This driver is a replacement for (and was inspired by) an older
768 driver named i2c-philips-par. The new driver supports more devices,
769 and makes it easier to add support for new devices.
