I also see this:

Here is what I get in /proc/device_tree:

Under that I see:

lutz:/proc/device-tree# grep -r -i fsl .

The contents of that file:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
fsl-i2c^@
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

Is there any further information that I can provide so that we can get
things fixed?

Thanks,
