Subject: [net-next v4 12/12] ASoC: SOF: ops: Add new op for client registration
From: Ranjani Sridharan <ranjani.sridharan@...ux.intel.com>
Add a new op for registering clients. The clients to be
registered depend on the DSP capabilities and the ACPI/DT
information. For now, we only add 2 IPC test clients that
will be used for run tandem IPC flood tests for all Intel
platforms.
For ACPI platforms, change the Kconfig to select
SND_SOC_SOF_PROBE_WORK_QUEUE to allow the virtbus driver
to probe when the client is registered.
