Adding more: I did ask in the past to properly represent SoM and
carriers. I pointed to other examples how this is done correctly. I did
look now inside and found absolutely no reference of actual product
called "Hamoa IoT" or "Purwa IoT". For sure there is no "Hamoa IoT Come"
SoM (sometimes COMe appears).

Look, this is a SoM:
https://www.toradex.com/computer-on-modules/verdin-arm-family/nxp-imx95

And you can find corresponding bindings and DTS in tree.

I refuse to accept more of this fake products trying to imitate well
known industry standards in their own way and effectively pushing some
downstream crap, just because that's how we do it in downstream.

Unless you can present us with such product details matching what you
send, I will be NAK-ing these and future patches like that.

Best regards,
