      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.

      Coarsely route HDMI diff pairs from the SoM to the CMF&ESD chips, place the microphone in a position that does not interfere with either the HDMI circuit or the RJ45
      
      The HDMI diff pairs will need to try to have 30mil clearance between each other at every point possible, in tight spaces this is not possible, even spacing will need to be adjusted in the following commit.

      Begin routing the HDMI circuit · 8c2544ff
      Eric Kuzmenko authored
      Needed to create the HDMI_HEAC_P/N labels to route Utility&HPD as diff pairs. Made cap C1905 NC, which is in parallel with a 0Ohm resistor between the HDMI sheilding and GND.

      Now using GPIO5_IO03 (P4.03) to put the class-D op-amp in shutdown and conserve energy when muted, make C1716 near the ETH PHY's DVDDL pin 47 220nF instead of 10uF (EmCraft suggested that this should be 100nF but their's is 220nF, asked why), added a 10k pull-down to PAM2841's ENA pin, added a 100nF cap to the smart card's C1 VCC pin, added a 1uF cap to the haptic motor circuit's 3V3_P rail
      
      Still need to use I2C3 instead of I2C1 according to EmCraft's suggestions.
