51      components;  each entry is a pair of strings, the first being the
52      connection's sink, the second being the connection's source;
53      valid names for sources and sinks are the WM8994's pins (as
54      documented in its binding), and the jacks on the board -
55      For samsung,aries-wm8994: HP, SPK, RCV, LINE, Main Mic, Headset Mic,
