-TDM slot:
-
-This specifies audio DAI's TDM slot.
-
-TDM slot properties:
-dai-tdm-slot-num : Number of slots in use.
-dai-tdm-slot-width : Width in bits for each slot.
-dai-tdm-slot-tx-mask : Transmit direction slot mask, optional
-dai-tdm-slot-rx-mask : Receive direction slot mask, optional
-
-For instance:
-	dai-tdm-slot-num = <2>;
-	dai-tdm-slot-width = <8>;
-	dai-tdm-slot-tx-mask = <0 1>;
-	dai-tdm-slot-rx-mask = <1 0>;
-
-And for each specified driver, there could be one .of_xlate_tdm_slot_mask()
-to specify an 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.
-
-The explicit masks are given as array of integers, where the first
-number presents bit-0 (LSB), second presents bit-1, etc. Any non zero
-number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask()
-does not do anything, if either mask is set non zero value.
