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.
|
||
|
|
|
||
|
|
For instance:
|
||
|
|
dai-tdm-slot-num = <2>;
|
||
|
|
dai-tdm-slot-width = <8>;
|
||
|
|
|
||
|
|
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.
