| description: Slot mask for active TDM slots. Optional. Drivers may |
| specify .xlate_tdm_slot_mask() to generate a slot mask dynamically. If |
| neither this property nor a driver-specific function are specified, the |
| default snd_soc_xlate_tdm_slot_mask() function will be used to generate |
| a mask. The first element of the array is slot 0 (LSB). Any nonzero |
| value will be treated as 1. |

| '^dai-tdm-slot-[rt]x-idle-mask$': |
| $ref: /schemas/types.yaml#/definitions/uint32 |
| description: Idle slot mask. Optional. A bit being set to 1 indicates |
| that the corresponding TDM slot is inactive/idle. |
