The pictures I could find via internet search engine make it look like
the name of the SoM is

SOM-IMX8MMLPD4

or similar. That silkscreen label is right below the EMTOP logo.

Can you please check that on your module ?

Hi,

> Yes, it is SOM-IMX8MMLPD4.

In that case, have a look at e.g. this "dh,imx8mp" system. That's also a
SoM and a carrier board (PDK3). Notice the structure, where both carrier
board compatible and SoM compatible and imx8mp compatible are listed in
the DT. I suspect you want to reproduce the same -- include both SoM and
carrier board compatible string.
