[PATCH 17/18] ASoC: SOF: topology: Make widget binding IPC agnostic
Ranjani Sridharan
ranjani.sridharan at linux.intel.com
Mon Mar 14 21:05:19 CET 2022
Make widget binding in the topology parser IPC agnostic by introducing a
new op, bind_event, in struct ipc_tplg_widget_ops. Also set the op
for all widget types in the IPC3 topology ops.
