A true mainline Linux Kernel for the Pinebook Pro

[tsys]

I tested today with all three of my USB-C to HDMI adapters... all can put up a display (and are reversible).

Thanks for testing! Kind of expected my cable to be at fault here.

Only odd thing is that one of the adapters doesn't seem to pass through the charger correctly. This is very likely to be an adapter problem rather than a PBP problem.

There are two debug logs, /sys/kernel/debug/usb/fusb302-4-0022 and /sys/kernel/debug/usb/tcpm-4-0022 in case you are interested in digging into USB typec configuration channel defails  

With a slightly more "better" (more expensive and more attractive) adapter then I can have one type-C connected to the board and it is providing a bunch of USB peripherals, HDMI output and is charging at 12W.

Huh, I'm not sure if I'm understanding you correctly here. Did you actually try a nicer adapter or would you just like to have one for the PBP? Would be totally amazing if it does actually work already since I had no way to even test that yet
