hell yeah, got displayport alt mode over usb-c working on rk3588 pocket reform with mainboard 2.0!

in the end it was a DP lane polarity issue: USB3 allows lane polarity swap for better PCB routing, but DP doesn't. tricky when you need to reuse the same lanes for both.

but wait... does that mean MNT Pocket Reform can have 3 displays now (1 DP, 1 HDMI, 1 internal)? yes, yes it can!

@alisynthesis @mntmn I feel we need to somehow stuff the pocket reform mainboard into a classic reform case to have the classic reform have feature parity compared to the pocket reform (not just because of display port alt mode over usb-c but also because the pocket has wifi, bluetooth and umts with rk3588...)

@josch @alisynthesis @mntmn imagine the batteries you could get in there with a tiny mainboard!

@tj @alisynthesis @mntmn More seriously I am hoping that we can re-use the Reform Next mainboard in the classic Reform. It already has support for eight LiFePo4 batteries, for the panel and since the left/right port board are separate you could create a port board with full size ethernet for example. :)
