| 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. |
| dai-tdm-slot-tx-mask : Transmit direction slot mask, optional |
| dai-tdm-slot-rx-mask : Receive direction slot mask, optional |
| |
| For instance: |
| dai-tdm-slot-num = <2>; |
| dai-tdm-slot-width = <8>; |
| dai-tdm-slot-tx-mask = <0 1>; |
| dai-tdm-slot-rx-mask = <1 0>; |
| |
| 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. |
| |
| The explicit masks are given as array of integers, where the first |
| number presents bit-0 (LSB), second presents bit-1, etc. Any non zero |
| number is considered 1 and 0 is 0. snd_soc_of_xlate_tdm_slot_mask() |
| does not do anything, if either mask is set non zero value. |
