[alsa-devel] Question about TDM "slot"

Hi

I would like to ask you about what does TDM "slot" mean on snd_soc_of_parse_tdm_slot() / snd_soc_dai_set_tdm_slot(). Is slot = 3 in this case ?

| |--- 2ch --> | | | CPU |--- 2ch --> | Codec | | |--- 2ch --> | | total 6ch

If this is correct, I have other question about slot_width. snd_soc_dai_set_tdm_slot comments say

slot_width: Width in bits for each slot.

Does this mean it will be 2ch x system word bit ? I know some codec chip have below style. Does it unexpected ?

| |--- 8ch --> | | | CPU |--- 4ch --> | Codec | total 12ch
