Commit Message

Ranjani Sridharan June 9, 2022, 3:26 a.m. UTC 
Define the prepare op for the DAI 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.
