1TDM slot: 2 3This specifies audio DAI's TDM slot. 4 5TDM slot properties: 6dai-tdm-slot-num : Number of slots in use. 7dai-tdm-slot-width : Width in bits for each slot. 8dai-tdm-slot-tx-mask : Transmit direction slot mask, optional 9dai-tdm-slot-rx-mask : Receive direction slot mask, optional 10 11For instance: 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>; 16 17And for each specified driver, there could be one .of_xlate_tdm_slot_mask() 18to specify an explicit mapping of the channels and the slots. If it's absent 19the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the 20tx and rx masks. 21 22For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit 23for an active slot as default, and the default active bits are at the LSB of 24the masks. 25 26The explicit masks are given as array of integers, where the first 27number presents bit-0 (LSB), second presents bit-1, etc. Any non zero 28number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask() 29does not do anything, if either mask is set non zero value. 30
