10 - Herve Codina <herve.codina@bootlin.com>
13 The IDT821034 codec is a four channel PCM codec with onchip filters and
14 programmable gain setting.
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 ALSA sound card node for
19 sub-nodes that involve the codec. The codec uses one 8bit time-slot per
21 'dai-tdm-tdm-slot-with' must be set to 8.
23 The IDT821034 codec also supports 5 gpios (SLIC signals) per channel.
