SoundWire support on Intel platforms relies on ACPI _ADR fields exposed in DSDT tables, with a 64-bit value defining which link a Slave device is connected to and its partId/manufacturerID/uniqueID. The existing definitions based on a globally-visible _HID used for I2C/I2S are no longer sufficient and need to be extended to detect during the probe steps which machine driver should be selected. This patchset adds the structure changes, and a set of static tables already used by Intel developers and customers. These tables are provided ahead of time, but they will only be used once all SoundWire-related parts are merged upstream and SoundWire is enabled in the builds.
