Stefan suggested that I try to address the comments against the PPC4xx
SPI driver, so here goes...
A post of version 7 of the driver will follow this email, but I thought
it might make it easier on everyone to inline my comments here. Hence,
this brief, introductory "top post".

Lesson #1: make sure your Subject: lines match the message
topic (I did a partial repair) and don't post to the wrong
list (e.g. PPC lists for OMAP questions).

Hi
i am a newbie and am doing a project on beagle board(running
omap3530). i am interfacing an adc(ads7886) to the beagleboard via
spi. need to know how the spi works and how a module can access the
spi registers of the omap. if someones already made an adc driver can
they mail me?
thanks

Note that given some patches now in the mm tree, this needs
something like the appended fixup. Some common code has now
moved into the spi core.
