On most hardware platforms, SoundWire interfaces are pin-muxed with other interfaces (typically DMIC or I2S) and the status of each link needs to be checked at boot time. For Intel platforms, the BIOS provides a menu to enable/disable the links separately, and the information is provided to the OS with an Intel-specific _DSD property. The same capability will be added to revisions of the MIPI DisCo specification.
