OK, does patch 3/4 not already contain what you are looking for? See:

http://ozlabs.org/pipermail/linuxppc-dev/2009-March/069787.html

I separated it from the NAND patches because they go through the MTD
maintainer(s).

BTW: did you have a chance to look into the following RFC on I2C bus
speed setting?

Thanks,
