PROTOCOLS
TripPoint
Defined in fuchsia.hardware.trippoint/trippoint.fidl
The server should enforce that only one client may be connected and configuring trip points at any given time. If a second client attempts to configure trip points while a client is already connected, the server should return ZX_ERR_ALREADY_BOUND to indicate that it is busy. The server may allow multiple clients to access the
