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.

title: Tegra210 ADMAIF
|
|
|
|
description: |
|
|
ADMAIF is the interface between ADMA and AHUB. Each ADMA channel
|
|
that sends/receives data to/from AHUB must interface through an
|
|
ADMAIF channel. ADMA channel sending data to AHUB pairs with ADMAIF
|
|
Tx channel and ADMA channel receiving data from AHUB pairs with
|
|
ADMAIF Rx channel.

Contains list of ACIF (Audio CIF) port nodes for ADMAIF channels.
|
|
The number of port nodes depends on the number of ADMAIF channels
|
|
that SoC may have. These are interfaced with respective ACIF ports
|
|
in AHUB (Audio Hub). Each port is capable of data transfers in
|
|
both directions.
