1 TDM slot: 2 3 This specifies audio DAI's TDM slot. 4 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 10 11 For 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 17 And for each specified driver, there could be one .of_xlate_tdm_slot_mask() 18 to specify an explicit mapping of the channels and the slots. If it's absent 19 the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the 20 tx and rx masks. 21 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 24 the masks. 25 26 The explicit masks are given as array of integers, where the first 27 number presents bit-0 (LSB), second presents bit-1, etc. Any non zero 28 number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask() 29 does not do anything, if either mask is set non zero value.
