From: Philippe Schenker <philippe.schenker@xxxxxxxxxxx> Toradex does provide device-tree overlays to enable certain evaluation hardware. Keep the buses disabled by default to be enabled again with overlays. For customers including this device-tree this has also the advantage that the hardware we want by default running does not automatically enable signals on their end.
