It doesn't depend +on the parport driver, and uses direct I/O access instead. This might be +preferred on embedded systems where wasting memory for the clean but heavy +parport handling is not an option. The drawback is a reduced portability +and the impossibility to daisy-chain other parallel port devices. + +Please see i2c-parport for documentation. + +Module parameters: + +* type: type of adapter (see i2c-parport or modinfo) + +* base: base I/O address + Default is 0x378 which is fairly common for parallel ports, at least on PC. + +* irq: optional IRQ + This must be passed if you want SMBus alert support, assuming your adapter + actually supports this. |
