56      List of the connections between audio
57      components;  each entry is a pair of strings, the first being the
58      connection's sink, the second being the connection's source;
59      valid names for sources and sinks are the MAX98090's pins (as
60      documented in its binding), and the jacks on the board.
61      For Odroid X2: "Headphone Jack", "Mic Jack", "DMIC"
62      For Odroid U3, XU3: "Headphone Jack", "Speakers"
63      For Odroid XU4: no entries
64      Deprecated, use audio-routing.
