It looks like you have some issue with your device tree. Did you add an overlay? Is so, what is it? For the RPI4 on OpenWrt, this looks something like:

(note that you’ll need to add that fragment to the overlays Makefile - e.g. morse-feed/examples/bcm27xx/target/linux/bcm27xx/patches-5.15/991-dt-overlays-build-morse-overlays.patch at mm/openwrt-23.05 · MorseMicro/morse-feed · GitHub - then add a line like dtoverlay=mm_wlan to your /boot/config.txt)
Someone else brought up the rpi5 here, so you may want to look at their overlays (and packages, for that matter): HaLow Integration on Raspberry Pi 5
