Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

This driver is a light version of i2c-parport. It doesn't depend
on the parport driver, and uses direct I/O access instead. This might be

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.
i2c-parport-light: Add SMBus alert support Add support for the SMBus alert mechanism to the i2c-parport-light driver. The ADM1032 evaluation board at least is properly wired for this.

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.
