| 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 | |
| 9 | For instance: |
| 10 | dai-tdm-slot-num = <2>; |
| 11 | dai-tdm-slot-width = <8>; |
| 12 | |
| 13 | And for each spcified driver, there could be one .of_xlate_tdm_slot_mask() |
| 14 | to specify a explicit mapping of the channels and the slots. If it's absent |
| 15 | the default snd_soc_of_xlate_tdm_slot_mask() will be used to generating the |
| 16 | tx and rx masks. |
| 17 | |
| 18 | For snd_soc_of_xlate_tdm_slot_mask(), the tx and rx masks will use a 1 bit |
| 19 | for an active slot as default, and the default active bits are at the LSB of |
| 20 | the masks. |
