9.2.2.2.2.6 TS3DS10224 SBU Mux for AUX and LSTX/RX

The SBU signals must be muxed from the Type-C connector to the Thunderbolt controller. The AUX for DisplayPort and LSTX/RX for Thunderbolt are connected to the TS3DS10224 and then muxed to the SBU pins. The SBU mux is controlled through GPIOs from the TPS65987DDJ. The table below shows the TPS65987DDJ GPIO events and the control signals from the TS3DS10224.
