- Basic driver which does minimum intialization of the Le88266 SLIC device.
- The code was originally borrowed from Zarlink driver implementation.
- It is not full fledged SLIC driver code, it just does basic
initialization which is required to setup a voice data path between
channels. This is just enough to test and demonstrate TDM functionality
on Freescale platforms using TDM Test Module.
- For full fledged VoIP type of use case proper SLIC driver will be required
which handles all the functionalities of the device.
- Going forward this driver will be replaced by Opoen source Zarlink APIs.

This is a small test module to transfer and receive data via tdm.
Registers with the TDM core and sets up a TDM voice path
between two TDM channels.
It support voice path demo using Le88266 SLIC device.

Freescale TDM controller consists of a TDM module supporting 128 channels
running at up to 50 Mbps with 8-bit and 16-bit word size. The TDM bus connects
gluelessly to most T1/E1 frames as well as to common buses such as the H.110,
SCAS, and MVIP. TDM also supports an I2S mode. The TDM module operates in
independent or shared mode when receiving or transmitting data.
This controller is available on MPC8315, P1010, P1020, P1022 and P1024 Freescale SOCs.
The driver registers itself with the TDM Framework & provides TDM functionality to the client modules.
In its present form this driver supports only channelised mode.

TDM Framework is an attempt to provide a platform independent layer which can offer a standard interface for TDM access to different client modules.
Beneath, the framework layer can house different types of TDM drivers to handle various TDM devices, the hardware intricacies of the devices being completely taken care by TDM drivers.
This framework layer will allow any type of TDM device to hook with it.
For example Freescale controller as on MPC8315, UCC based TDM controller, etc
The main functions of this Framework are:
- provides interface to TDM clients to access TDM functionalities.
- provides standard interface for TDM drivers to hook with the framework.
- handles various data handling stuff and buffer management.
In future this Framework will be extended to provide Interface for Line control devices also. For example SLIC, E1/T1 Framers etc.
Presently the framework supports only Single Port channelised mode.
Also the configurability options are limited which will be extended later on.
Only kernel mode TDM clients are supported currently. Support for User mode clients will be added later.
