Thanks for this patch. Maybe it would make sense also to enable I2C
controller,
which is also available on the external connector?
Then I would also like to add some kind of comment in the DTS on which
pins given
bus/feature is available. This should help a lot people trying to
connect external
sensors to the Odroid boards.
For this patch:
