A true mainline Linux Kernel for the Pinebook Pro

more good news: DP altmode on the USB-C port is now working!

Support is not perfect and pretty hacky but it should still work just fine. It does only work in one USB-C plug orientation for me though. Since it does only work in one orientation on the stock debian image, too I'm currently suspecting my USB-C -> HDMI cable. Unfortunately I do not have any other device that can do USB-C DP altmode thus I can't really test that hypothesis.

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

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. 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.
