Rev. 1.1 5
1 Introduction
This document describes the capabilities of the 73M1822/73M1922 Hardware Module for the SMDK2412.
This driver software is provided for use and integration by Teridian customers on their individual
platforms.
Throughout this document the 73M1822/73M1922 Hardware Module for the SMDK2412 is simply referred
to as “driver” or “device driver”. The 73M1822 and 73M1922 is collectively referred to as the 73M1x22 or
the device.
1.1 Purpose and Scope
The 73M1822/73M1922 Hardware Module for the SMDK2412 provides the necessary system interfaces
for the control and management of the 73M1x22. The driver supports calls from a user space application
or kernel module and translates these to and from the device. The driver can be used as is, in whole or in
part, or customized to accommodate a customer’s unique environment.
The scope of this document includes discussion of driver’s architecture and design and interface to the
user. The 73M1822/73M1922 Hardware Module for the SMDK2412 is intended specifically for the
Samsung S3C2412 processor on the SMDK2412 development board and for the Linux
®
operating system
version 2.6.19 as customized by Samsung for the aforementioned system. Layers above the reference
driver address software interfaces which may pre-exist for a given application and the layer below
addresses hardware related interfaces between the processor and the 73M1x22 device.
