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 PEQ
|
|
|
|
description:
|
|
The Parametric Equalizer (PEQ) is a cascade of biquad filters with
|
|
each filter tuned based on certain parameters. It can be used to
|
|
equalize the irregularities in the speaker frequency response.
|
|
PEQ sits inside Output Processing Engine (OPE) which interfaces
|
|
with Audio Hub (AHUB) via Audio Client Interface (ACIF).
