I can see how to wire this up, use the processor as SPI master and
the ADC as
SPI slave, get the clock running, etc. I n

OK.

Hi,
I'm currently working on a driver to talk to an analog-to-digital
converter (specifically a Texas Instruments ADS1672) connected to the
McBSP port on a Beagleboard-xM. I'm currently building my driver module
against a 3.2 series kernel with Beagleboard patches and config from
