This patch adds the slot parsing from DT supports. TDM slot properties: dai-tdm-slot-num : Number of slots in use. dai-tdm-slot-width : Width in bits for each slot. For instance: dai-tdm-slot-num = <2>; dai-tdm-slot-width = <8>; And for each spcified driver, there could be one .of_xlate_tdm_slot_mask() to specify a explicit mapping of the channels and the slots. If it's absent the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the tx and rx masks. For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit for an active slot as default, and the default active bits are at the LSB of the masks.
