From: Frank Wunderlich <frank-w@public-files.de>

Sinovoip has released other variants of Bananapi-R4 board.
The known changes affecting only the LAN SFP+ slot which is replaced
by a 2.5G phy with optional PoE.

As the SFP-Ports are not upstreamed yet this patch simply renames the
current board dts to dtsi, creating new dts for the board including
the new dtsi and move i2c-mux channel for sfp lan to board dts.

I understand what's going on, and I agree, but this change alone doesn't make a lot
of sense, does it?

If I were to see a commit that moves everything in a dtsi, and justifies that by
adding two dts for the two variants, though, things would be different.... :-)

Cheers,
Angelo

It is preparation for adding additional nodes like sfp cages. I only have the dual-sfp board so i can only add these based on schematic. The one (wan-sfp) would go into dtsi and lan-sfp go into dts because other variants using a phy here as described.

what is the difference to this commit (imho it does basicly the same for other SoC)?
