7 title: Tegra210 ADX Device Tree Bindings
10 The Audio Demultiplexer (ADX) block takes an input stream with up to
11 16 channels and demultiplexes it into four output streams of up to 16
12 channels each. A byte RAM helps to form output frames by any combination
13 of bytes from the input frame. Its design is identical to that of byte
14 RAM in the AMX except that the data flow direction is reversed.

47 ADX has one input and four outputs. Accordingly ACIF (Audio Client
48 Interface) port nodes are defined to represent ADX input (port 0)
49 and outputs (ports 1 to 4). These are connected to corresponding
50 ports on AHUB (Audio Hub).
