title: Infineon PEB2466 codec

description: |
  The Infineon PEB2466 codec is a programmable DSP-based four channels codec
  with filters capabilities.

  The time-slots used by the codec must be set and so, the properties
  'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and
  'dai-tdm-slot-rx-mask' must be present in the sound card node for sub-nodes
  that involve the codec. The codec uses one 8bit time-slot per channel.
  'dai-tdm-tdm-slot-with' must be set to 8.

  The PEB2466 codec also supports 28 gpios (signaling pins).
