### Function topology

A function topology provides generic and basic audio path for an individual hardware function, such
as headset, amplifier or microphone. The Linux kernel driver uses function information exposed by
ACPI when selecting and loading the corresponding topology.
Function topologies are intended to be reusable across devices that provide the same function.
Please do not add any customized feature in the function topology.
