You can also dump the entire ACPI using acpudump from acpica-tools (it may be packaged under a different name in your distribution).
Sometimes devices may be flashed with different versions of coreboot firmware which contain different _DSD values. When debugging, it's helpful to know the exact platform data seen by a codec driver.
Sure, but that's hardly driver specific so the firmwares provide infrastructure for this.
