I am sorry for the confusion of the schematic. Please ignore the power
tree on sheet 3, it's from the original reference design, I think we
have different power paths on ROCK Pi 4. Please refer the circuits
starting from sheet 5 below. It reflects the real hardware. We will
fix the power tree and upload a new version of the schematic.
