The DSPless mode of the ASoC/SOF driver can be used for hardware verification and debug on platforms with HDaudio codecs. The DSP mode is still needed on existing platforms for SSP, DMIC, SoundWire interfaces managed by the GP-DMA. This mode is also helpful to compare the legacy HDaudio driver with the ASoC/SOF driver wrt. codec management and handling. In theory we use the same code but differences are sometimes seen on jack detection and event handling.
