-ASoC Simple SCU Sound Card
-
-Simple SCU Sound Card is "Simple Sound Card" + "ALSA DPCM".
-For example, you can use this driver if you want to exchange sampling rate convert,
-Mixing, etc...
-
-Required properties:
-
-- compatible                           : "simple-scu-audio-card"
-                                         "renesas,rsrc-card"
-Optional properties:
-
-- simple-audio-card,name               : see simple-audio-card.txt
-- simple-audio-card,cpu                        : see simple-audio-card.txt
-- simple-audio-card,codec              : see simple-audio-card.txt
-
-Optional subnode properties:
-
-- simple-audio-card,format             : see simple-audio-card.txt
-- simple-audio-card,frame-master       : see simple-audio-card.txt
-- simple-audio-card,bitclock-master    : see simple-audio-card.txt
-- simple-audio-card,bitclock-inversion : see simple-audio-card.txt
-- simple-audio-card,frame-inversion    : see simple-audio-card.txt
-- simple-audio-card,convert-rate       : platform specified sampling rate convert
-- simple-audio-card,convert-channels   : platform specified converted channel size (2 - 8 ch)
-- simple-audio-card,prefix             : see routing
-- simple-audio-card,widgets            : Please refer to widgets.txt.
-- simple-audio-card,routing            : A list of the connections between audio components.
-                                         Each entry is a pair of strings, the first being the connection's sink,
-                                         the second being the connection's source. Valid names for sources.
-                                         use audio-prefix if some components is using same sink/sources naming.
-                                         it can be used if compatible was "renesas,rsrc-card";

-Required CPU/CODEC subnodes properties:
-
-- sound-dai                            : see simple-audio-card.txt
-
-Optional CPU/CODEC subnodes properties:
-
-- clocks / system-clock-frequency      : see simple-audio-card.txt
