-Kernel driver i2c-taos-evm
-Author: Jean Delvare <>
-This is a driver for the evaluation modules for TAOS I2C/SMBus chips.
-The modules include an SMBus master with limited capabilities, which can
-be controlled over the serial port. Virtually all evaluation modules
-are supported, but a few lines of code need to be added for each new
-module to instantiate the right I2C chip on the bus. Obviously, a driver
-for the chip in question is also needed.
-Currently supported devices are:
-For additional information on TAOS products, please see
-Using this driver
-In order to use this driver, you'll need the serport driver, and the
-inputattach tool, which is part of the input-utils package. The following
-commands will tell the kernel that you have a TAOS EVM on the first
-serial port:
-# modprobe serport
-# inputattach --taos-evm /dev/ttyS0
-Technical details
-Only 4 SMBus transaction types are supported by the TAOS evaluation
-* Receive Byte
-* Send Byte
-* Read Byte
-* Write Byte
-The communication protocol is text-based and pretty simple. It is
-described in a PDF document on the CD which comes with the evaluation
-module. The communication is rather slow, because the serial port has
-to operate at 1200 bps. However, I don't think this is a big concern in
-practice, as these modules are meant for evaluation and testing only.
