   1 TDM slot:
   2
   3 This specifies audio DAI's TDM slot.
   4
   5 TDM slot properties:
   6 dai-tdm-slot-num : Number of slots in use.
   7 dai-tdm-slot-width :  Width in bits for each slot.
   8
   9 For instance:
  10         dai-tdm-slot-num = <2>;
  11         dai-tdm-slot-width = <8>;
  12
  13 And for each spcified driver, there could be one .of_xlate_tdm_slot_mask()
  14 to specify a explicit mapping of the channels and the slots. If it's absent
  15 the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the
  16 tx and rx masks.
  17
  18 For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
  19 for an active slot as default, and the default active bits are at the LSB of
  20 the masks.
