The mailinglist mostly has patches on it, so I don't really know if
people are expecting non-patch mails.

If in doubt the #linux-rockchip channel on the libera.chat IRC network [0]
might help more. (people in different timezones, so probably no immediate
answers)



For the multi-pci case I guess you could start by looking at other rk3568
board doing similar things, like the Qnap-TS433 [1], Radxa E25 [2] or
Nanopi-R5S [3].

Generally board designers often follow reference designs, so things might
be similar.

Similarly, you might want to push your current in progress work on some
github thing, so people can take a look.


It also looks like the H68KV2 variant of the device has schematics
available as linked from the bottom of [4], not sure how that relates
to your device though.
