Generally fine, a few remarks below.

Should be good to merge after those are resolved.

Add
	mediatek,mtd-eeprom = <&factory 0x0>;
here

Convert to nvmem here. (You will also need to add the corresponding node at
the end of the file; just look at recent versions of the other wavlink
devices)

This means port 4 would be wan. You configure it as lan.
You should probably choose a different portmap here.

Switch the two lines here to have proper alphabetic sorting.

This should be dropped, the device only has one port set as LAN by default.
