1TDM slot:

3This specifies audio DAI's TDM slot.

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