ASoC: fsl_sai: add xlate_tdm_slot_mask() callback

Browse source

With DPCM case, for example ASRC->SAI->AMIX, the SAI can be codec dai
device in backend, but __soc_pcm_hw_params() will get the tdm_mask
for channel constraint, tdm_mask is set by snd_soc_dai_set_tdm_slot()
from slot number, but SAI supports flexible channel number with fixed slot
number, so add an empty xlate_tdm_slot_mask() callback to avoid the
channel constraint in __soc_pcm_hw_params().
