Add Tegra264 compatible strings to APE subsystem device bindings: - audio-graph-card: Due to different PLL clock rate. - admaif: Due to 32 channels supported and register offset changes. - i2s: Due to 32 channels supported and register offset changes. - amx/adx: Due to 32 channels supported and register offset changes. - asrc: Due to different ARAM address. - ahub: Due to AHUB IPs number of instances updates. - for future proofing the T264 compatibility is added for other device nodes. These bindings enable the enhanced audio features of Tegra264 while maintaining compatibility with existing platforms.

|
|
The Audio Demultiplexer (ADX) block takes an input stream with up to
|
|
16 channels and demultiplexes it into four output streams of up to 16
|
|
channels each. A byte RAM helps to form output frames by any combination
|
|
of bytes from the input frame. Its design is identical to that of byte
|
|
RAM in the AMX except that the data flow direction is reversed.

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