Hi!
Configurations with multiple codecs attached to the platform are supported but only if each from the set is different. Add new field representing the 'Unique ID' so that codecs that share Vendor and Part IDs can be differentiated and thus enabling support for such configurations.
Apparently this is preparation for something, but we should not need it in AUTOSEL as noone will write the uid here.
Best regards, Pavel
