title: Renesas IDT821034 codec device

description: |
The IDT821034 codec is a four channel PCM codec with onchip filters and
programmable gain setting.
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 ALSA 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 IDT821034 codec also supports 5 gpios (SLIC signals) per channel.
