Hi guys,

I know the I2C stuff is up in the air (I cannot pinpoint the documentation
for it) and have not found any CAN bus documentation for device trees.

I want to update the firmware tree to add these but, am basically looking
for those docs, or someone to go over a few points.. is there some kind of
tree standard I should be looking at, or some patch I missed which has
a driver which implements something that looks at a compatible tree?

I think some consensus has been achieved for describing i2c busses and
their attached devices, but I don't think booting-without-of.txt has
been updated with the details yet.  I need to look into that more.

I don't think anyone has tackled CAN.  Best bet is to draft a tree in
the way you think it should be described and post it to the list.
That will give a starting point for us to discuss it and come to
consensus.

For MSCAN on the MPC5200 we currently have:

		mscan@900 {
			device_type = "mscan";

These device_type entries should not be here.
