Bug=None
Test=Enabled the device on TGLY RVP and tested that the codec is
reflected in SSDT. Checked sound card binding works
and soundwire drivers are enabled in kernel.

The ALC5682 headset codec can be connected over SoundWire and be
configured for mainboards to use:
- Data Port 0 and Bulk Register Access is supported
- Data Ports 1-4 are supported as both source and sink
The data port and audio mode properties are filled out as best as
possible with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 0 and has strap
settings configuring it for unique ID 1:
chip drivers/soundwire/alc5682
register "desc" = ""Headset Codec""
device generic 0.1 on end
end
This driver was tested with the volteer reference design by booting
and disassembling the runtime SSDT to ensure that the devices have the
expected address and properties.

The MAX98373 smart speaker amp can be connected over SoundWire and be
configured for mainboards to use:
- Data Port 0 and Bulk Register Access is not supported
- Data Port 1 is the 32bit data input for the speaker path
- Data Port 3 is the 16bit data output for I/V sense ADC path
The data port and audio mode properties are filled out as best as
possible with the datasheet as a reference.
The ACPI address for the codec is calculated with the information in
the codec driver combined with the devicetree.cb hierarchy where the
link and unique IDs are extracted from the device path.
For example this device is connected to master link ID 1 and has strap
settings configuring it for unique ID 3.
chip drivers/soundwire/max98373
register "desc" = ""Left Speaker Amp""
device generic 1.3 on end
end

This header implements structures to describe the properties defined in
the SoundWire Discovery and Configuration Specification Version 1.0.
By itself this just provides the property definitions, it is then used
by the code that generates ACPI device properties and by the controller
and codec drivers.
A new header for MIPI vendor/device IDs is also added, with the MIPI
Alliance board members added by default. This will be used in the same
way as pci_ids.h to track devices added to coreboot.
