As far as I'm concerned, yes.  Everything points to "CoolPi CM5"
and "CoolPi GenBook" being the rigth names in the upstream kernel
for the SoM and the carrier board, respectively.

However, please see another comment below.

It would be better to omit "RK3588" from the model name and use
"CM5" instead, because that more precisely reflects the "dependency
graph", so to speak.  Thus, I'd suggest that "CoolPi CM5 GenBook"
is used as the model name.

Technically, "CoolPi CM5 on GenBook carrier board" would be a more
correct model name, so that's another option, but the above-proposed
"CoolPi CM5 GenBook" sounds more like a finished product/device
than just some carrier board with an SoM.
