Tom,
thanks for your answer.
Yes, I am interested on having the MPC826x CPM i2c algorithm in the
kernel.
Find the i2c-8260 patch enclosed.
I took Denx's 2.4.x based implementation and ported it to 2.6.7 and later
to 2.6.9.
In addition, I have patched the i2c-dev.h as recommended by the lmsensors
project in order to allow user space to perform ioctrl on the i2c device.
Regards.
Miguel
PS. I also have a patch for linux-2.6.7, if someone out there is
interested

OK.

Probably, but the OCP or platform_device work is something that needs to
get at some point. I'll take a look, if you're willing to push the
driver with upstream I2C folks.

The I2C list is at sensors at stimpy.netroedge.com, and should probably be
CC'd as well.
Thanks again.
