[PATCH 05/23] ASoC: SOF: ipc4-topology: Add prepare op for AIF type widgets
Ranjani Sridharan
ranjani.sridharan at linux.intel.com
Thu Jun 9 05:26:25 CEST 2022
Define the prepare op for the AIF type widgets for IPC4.
The prepare op is responsible for choosing the input/output audio
formats for these widgets based on the runtime PCM params, assigning the
instance ID and updating the total memory usage for the pipelines these
widgets belong to.
