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: NVIDIA Tegra ACONNECT Bus
|
|
|
|
description: |
|
|
The Tegra ACONNECT bus is an AXI switch which is used to connect various
|
|
components inside the Audio Processing Engine (APE). All CPU accesses to
|
|
the APE subsystem go through the ACONNECT via an APB to AXI wrapper. All
|
|
devices accessed via the ACONNECT are described by child-nodes.
