|
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).
