Doesn't this (and some others) also need status="disabled" since they're not present on MT7623A? Or maybe it's time to split mt7623.dtsi into a mt7623n.dtsi which includes mt7623a.dtsi and adds the extra components?
any opinions about this? should i disable all new nodes and enable them in the dts for specific board (bpi-r2/mt7623n-rfb)?
have prepared it here [1]
do you have a MT7623A board for testing? is there any list which components are existing on mt7623a? or should i disable all of them and re-enable them in bpi-r2 dts?
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*?
yes, bananapi r2 has external mt7530 switch connected to gmacs 0+1 with its ports 6+5
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.
or should we split dtsi to have a common part (mt7623.dtsi), and one for soc (mt7623n.dtsi/mt7623a.dtsi)?
mt7623.dtsi => mt7623n.dtsi => mt7623n-bananapi-bpi-r2.dts mt7623.dtsi => mt7623a.dtsi => mt7623a-unielec-u7623.dts (not existing yet, openwrt seems to use a board-specific dtsi)
