Can't the dai-tdm-* properties work for you?

We will register multiple codecs inside a single dai_link and differentiate these codecs by of_node. so we can't use dai-tdm-slot* to define the slot for each codec

Why do you need this?

When using multiple codecs, we utilize prefix_name to distinguish the dapm and kcontro of each individual codec.
