| 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. | 
 |  | 
 | 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. |
