@navi @novenary I actually have some WIP on that. To also power the whole thing with PD is more complicated than I'd imagined, and I need to ask more knowledgeable people. DP alt mode is also not that trivial, I think I know how though. Also, you can only have one Displayport sink; for more you need MST, and ICs for that are unobtainium. @mntmn maybe knows how to power a circuit from PD and provide charging, too?

@mntmn @novenary @navi thanks. my plan would be USB-C in (PD), USB-A 3.0 out, DP out (sink), and USB-C out with all those.

@mntmn @novenary @navi from the dock side, a sink (to the monitor)

@mntmn @novenary @navi yeah, I found that also confusing, but according to VESA, the sink is what receives the image

@navi @novenary @mntmn yes please, can also do a layout / circuit review if you like. Which chip could do PD/DP alt mode?

@mntmn @novenary @navi can do. FYI this is my WIP:

Will need to verify if this is correct with someone who knows more than I do; this is mostly based on TI's TIDA-01243
