 * @link_mask: describes required board layout, e.g. for SoundWire.

 * @board: board name
 * @machine_quirk: pointer to quirk, usually based on DMI information when
 * ACPI ID alone is not sufficient, wrong or misleading

 * audio codecs whose presence if checked with ACPI
 * @pdata: intended for platform data or machine specific-ops. This structure

 * @sof_tplg_filename: Sound Open Firmware topology file name, if enabled
