+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.

This one is never needed. Drop.

This should be rather unevaluatedProperties: false, so other properties
from spi-props and dai-common will work.

Node names should be generic, so "audio-codec"

Drop sound{} node. Not relevant to the case here and it's the same in
every case of audio codec... unless something here is specific. But even
the dai-tdm properties are sound card specific.

Indeed, I wanted to show the dai-tdm properties.
But ok, I will drop the node.
