Connecting A/D and D/A to SCC channels on a MPC860/MPC8260

Connecting A/D and D/A to SCC channels on a MPC860/MPC8260

[diekema_jon]

	* I am looking to connect serial A/D's and D/A's to one or more of
	the MPC860/MPC8260 SCC channels.  I will be working on a Linux
	device driver to support this hardware.  Has anybody worked on
	something like this before?  If so, would they be willing to share
	ideas, pitfalls, sample code, etc?

	Target hardware:

	48-96 Khz sampling
	22-24 bit

	Input:  4 A/D's
	Output: 2 D/A's

Use something that "frames" the data and the SI/TDM interface works
really sweet.  Take a look at the CS4218 audio codec driver I did
for the Embedded Planet boards.  It's floating around in the 2.2.13
kernels on the MontaVista site.
