The UniElec U7623 board (which is supported in OpenWrt) is MT7623A.
I was told that MT7623N has GPU and HDMI, while the MT7623A has a
built-in mt7530 switch. Does that imply the switch on the MT7623N
boards is *external*?
If so, that means that mt7623n.dtsi maybe shouldn't just include
mt7623a.dtsi because it's not a strict superset; maybe they should both
include a common mt7623.dtsi that has the parts that are truly common?
I also suspect the switch definition from the UniElec U7623 dts should
probably move to this new mt7623a.dtsi? That's not upstream yet though.
