Where does the name "cgi" come from and what does it mean?
Clock Generator Input? Does the sg2042 documentation call it that?

It's abbrevation of "Clock Gen IC", I found this in the clock tree diagram. https://github.com/sophgo/sophgo-doc/blob/main/SG2042/TRM/source/pic/clock-tree.png

BTW, There are three cgi on the diagram. Should I define 3 in DTS too? I just found they are the same so I just defined one.
