1 TDM slot:
3 This specifies audio DAI's TDM slot.
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 dai-tdm-slot-tx-mask : Transmit direction slot mask, optional
9 dai-tdm-slot-rx-mask : Receive direction slot mask, optional
12 	dai-tdm-slot-num = <2>;
13 	dai-tdm-slot-width = <8>;
14 	dai-tdm-slot-tx-mask = <0 1>;
15 	dai-tdm-slot-rx-mask = <1 0>;
20 tx and rx masks.
22 For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit
23 for an active slot as default, and the default active bits are at the LSB of
27 number presents bit-0 (LSB), second presents bit-1, etc. Any non zero
29 does not do anything, if either mask is set non zero value.
