Subject: [PATCH] ASoC:CNL: Add DAIS for SoundWire masters.
|
|
|
|
Add new DAIs for SoundWire master for aggregation.
|
|
Add DAI IDs to find the master controller from DAI.
|
|
Earlier DAI was found from the copier vbus, but with
|
|
aggregation, copier is linked to multiple DAIs which
|
|
are aggregated. So add be_ids range to idendify
|
|
SDW master controller from DAIs.
|
|
