I'll add some description about the file copy in commit message.

I'm sorry, I don't get your question here.
Anyway, the DT overlays are needed, because the 40-pin EXP/PRI interface on
the i.MX93 9x9 QSB board can not only connect to a DPI panel adapter board
but also to an audio hat[2], and maybe more.  The newly introduced .dtsi
file just aims to avoid duplicated code.
