A bit of an update for this thread, a solid-run developer has pushed their dts file into the kernel - 6.11. But there was also someone who added a dts file to openwrt github link.
There was a some re-factoring of the dts files for this board, so I assume when openwrt adopts a kernel with that version it will take all of those configs, and discard the existing file.
A related question to this - Would openwrt carry a patch on this dts file? I ask because solid-run indicated here that it is okay to remove the reference to the 6th ethernet port in the dts file. It is populated on the board but the enclosure they sell doesn't expose the port. I am surprised it made it in the upstream dts file, but solid-run know better than me why it is there.
I experienced some odd behavior when that 6th port was in the dts file. Before submitting a patch to remove it I would like to characterize the problem fully. The oddness I experienced might be related to the arguments supplied to ucidef_set_interfaces_lan_wan
