I2C and SMBus
=============
@@ -33,52 +31,17 @@ When we talk about I2C, we use the following terms:
Client
An Algorithm driver contains general code that can be used for a whole class

-driver.
+of I2C adapters. Each specific adapter driver either depends on one algorithm
+driver, or includes its own implementation.
A Driver driver (yes, this sounds ridiculous, sorry) contains the general
code to access some type of device. Each detected device gets its own
data in the Client structure. Usually, Driver and Client are more closely
integrated than Algorithm and Adapter.
-For a given configuration, you will need a driver for your I2C bus (usually
-a separate Adapter and Algorithm driver), and drivers for your I2C devices
-(usually one driver for each device). There are no I2C device drivers

-for device drivers.
+For a given configuration, you will need a driver for your I2C bus, and
+drivers for your I2C devices (usually one driver for each device).
At this time, Linux only operates I2C (or SMBus) in master mode; you can't
use these APIs to make a Linux system behave as a slave/device, either to
speak a custom protocol or to emulate some other device.
