FYI: I was wondering what the convention was when I submitted the
rk3568-rock-3a.dts. There are boards with the compatible
"radxa,rockpi4a", "radxa,rockpi4b", "radxa,rockpis", but also the
"radxa,rock-4c-plus". I went with the slight majority and named it
"radxa,rock3a". Maybe you would like to consider "radxa,rock5a" in order
to follow suit.
Best regards,
Michael
