    Subject[PATCH 7/8] dt-bindings: usb: Add binding for fcs,fsa4480
    Date
    The Fairchild/ON Semiconductor FSA4480 Analog Audio switch is used in
    USB Type-C configurations for muxing analog audio onto the USB
    connector, and as such used to control the SBU signals for altmodes such
    as DisplayPort.

    Add a binding for this hardware block.
