No problem. For me, the CI20 is also a hobby project :)
Here is some information about the CI20 WiFi and firmware:
https://elinux.org/CI20_Hardware#WiFi.2FBT
https://elinux.org/CI20_upstream#WiFi_firmware
So to be it looks as if the
compatible = "brcm,bcm4330-fmac";
is correct. But the reg = <4> or <1> is something we have to find out.
BR,
Nikolaus
