12description: |
13  The Infineon PEB2466 codec is a programmable DSP-based four channels codec
14  with filters capabilities.
15
16  The time-slots used by the codec must be set and so, the properties
17  'dai-tdm-slot-num', 'dai-tdm-slot-width', 'dai-tdm-slot-tx-mask' and
18  'dai-tdm-slot-rx-mask' must be present in the sound card node for sub-nodes
19  that involve the codec. The codec uses one 8bit time-slot per channel.
20  'dai-tdm-tdm-slot-with' must be set to 8.
21
22  The PEB2466 codec also supports 28 gpios (signaling pins).
