[PATCH 21/23] ASoC: SOF: ipc4-topology: Add support for SSP/DMIC DAI's
Ranjani Sridharan

Thu Jun 9 05:26:41 CEST 2022
The copier config for SSP and DMIC type DAI copiers needs to be parsed
and matched with the runtime hw_config from the NHLT table. Along with
this, also add the change to set the node_id for these copier types.
