MODULE: i2c-stub
DESCRIPTION:
This module is a very simple fake I2C/SMBus driver. It implements three
types of SMBus commands: write quick, (r/w) byte data, and (r/w) word data.
No hardware is needed nor associated with this module. It will accept write
quick commands to all addresses; it will respond to the other commands (also
to all addresses) by reading from or writing to an array in memory. It will
also spam the kernel logs for every command it handles.
The typical use-case is like this:
1. load this module
2. use i2cset (from lm_sensors project) to pre-load some data
3. load the target sensors chip driver module
4. observe its behavior in the kernel log
CAVEATS:
There are independent arrays for byte/data and word/data commands. Depending
on if/how a target driver mixes them, you'll need to be careful.
If your target driver polls some byte or word waiting for it to change, the
stub could lock it up. Use i2cset to unlock it.
If the hardware for your driver has banked registers (e.g. Winbond sensors
chips) this module will not work well - although it could be extended to
support that pretty easily.
If you spam it hard enough, printk can be lossy. This module really wants
something like relayfs.

The name can be chosen freely, and may be upto 40 characters long. Please
use something descriptive here.
The id should be a unique ID. The range 0xf000 to 0xffff is reserved for
local use, and you can use one of those until you start distributing the
driver. Before you do that, contact the i2c authors to get your own ID(s).
If used, the id should be a unique ID. The range 0xf000 to 0xffff is
reserved for local use, and you can use one of those until you start
distributing the driver, at which time you should contact the i2c authors
to get your own ID(s). Note that most of the time you don't need an ID
at all so you can just omit it.
Don't worry about the flags field; just put I2C_DF_NOTIFY into it. This
means that your driver will be notified when new adapters are found.
