title: Tegra210 AHUB

description: |
  The Audio Hub (AHUB) comprises a collection of hardware accelerators
  for audio pre-processing, post-processing and a programmable full
  crossbar for routing audio data across these accelerators. It has
  external interfaces such as I2S, DMIC, DSPK. It interfaces with ADMA
  engine through ADMAIF.

      Contains list of ACIF (Audio CIF) port nodes for AHUB (Audio Hub).
      These are connected to ACIF interfaces of AHUB clients. Thus the
      number of port nodes depend on the number of clients that AHUB may
      have depending on the SoC revision.
