*The Pre-Production Rev 1 files don't have eMMC-RCLK routed back to the SOM. As a result, a pin change was made on the SOM.

• J2 pin D5 was GND on Rev 1, is now Q0-4-L1 on Rev 3.
• J2 pin I2 was Q0-4-L1 on Rev 1, is now SDC1-RCLK on Rev 3.

80-001777RL-3	DP-HPD-3V3 is routed through the PCIe voltage translator (U26). As such, 3V3-PCIE must be enabled for the DP-HPD to function.
