Hi Michael,

Xianghua is trying to reach you to share your works on Motorola MPC
drivers, so I am forwarding his message to you so that you can get in

Subject: Question on I2C driver development for Motorola chips


I'm an engineer working in Motorola. I have a 'working' I2C driver for
the new chip MPC8540/MPC8560 and I'm eager to add this driver to your
CVS, and I hope it can be pushed to the linux kernel in the near future.

I noticed a MPC8245 I2C driver is under development by Mike Primm from
your newdriver
webpage(http://secure.netroedge.com/%7Elm78/newdrivers.html), and I'm
very interested in his progress, however there is no way for me to reach
him(there is no email address :( ). Additionally, there is another Linux
I2C driver for MPC824x(http://www.humboldt.co.uk/mpc10xi2c.html).
Include my driver, all of us are trying to do the same thing because
MPC8540/MPC8560/MPC824x/MPC107 are having the similar I2C design. I
would like to find a way to provide a generic I2C for all these Motorola

I'm also interested in getting the current Motorola 8xx I2C driver a new
name if possible, because that driver can also be shared by
8xx/82xx/83xx(forthcoming new chip), i.e. any Motorola chip with a
CPM(Communication Process Module) part on it.

Thanks a lot for your helps.
