Is there a way of changing the i2c speed to the 10kbs mode described in the
http://en.wikipedia.org/wiki/I%C2%B2C i2c wiki page?
We've got some i2c hardware that's a little on the flaky side still, and
some software development is getting blocked occasionally as a result. It
might help to bring the i2c at the lower speed.
I've seen the postings on setting it to the high speed mode with:
pxaregs ICR_FM 1
Is there a similar technique for setting to 'low' speed? I've looked
through the pxaregs 'help' but there doesn't seem to be anything documented.

The i2c hardware itself doesn't support that, but you could use the
linux support for bit-banged i2c using gpio lines. You need to create
your own adapter and implement the functions for setting the SDA and
SCL lines. But you can specify your own delay amount in microsconds.
