The new driver supports more devices, 753 and makes it easier to add support for new devices. 754 755 An adapter type parameter is now mandatory. Please read the file 756 Documentation/i2c/busses/i2c-parport for details. 757 758 Another driver exists, named i2c-parport-light, which doesn't depend 759 on the parport driver.

It doesn't depend 776 on the parport driver, and uses direct I/O access instead. This 777 might be preferred on embedded systems where wasting memory for 778 the clean but heavy parport handling is not an option. The 779 drawback is a reduced portability and the impossibility to 780 daisy-chain other parallel port devices. 781 782 Don't say Y here if you said Y or M to i2c-parport. Saying M to 783 both is possible but both modules should not be loaded at the same 784 time. 785 786 This support is also available as a module.
