Route USB2 to the hub chip's upstream port and re-order & route each of the downstream ports to their respective locations (smartcard, mPCIe, & M.2), place and route the HDMI fuse, schottky diodes, TVS diodes, capacitors, and pull-up resistors, route the rest of the HDMI's interface to the SoM (HPD & I2C), adjust the GNSS antenna's CPW width using the PCB manufacturer's recommendation from their calculations

The HDMI circuit should be complete now. The GNSS & WiFi+BT antennae should also be complete. The GNSS module's RX & TX lines need to be routed next.
