A true mainline Linux Kernel for the Pinebook Pro
#68
@tsys, Do you happen to know if the DP Alt-mode over USB-C is using 2 or 4 lanes?

If I understand DP Alt-mode correctly, (and it's possible I don't :-), if we use 2 lanes for DP, we can use the other 2 lanes for USB 3. This would allow some of the USB-C docks to have both video from the Pinebook Pro, (not USB device video), And USB 3 peripherals like Gigabit Ethernet and more USB 3 ports via a hub.

A drawback to using DP Alt-mode over 2 lanes is that it would limit the resolution or refresh rate. So it's a choice the user would have to make. Use a simple 4 lane DP Alt-mode to video adapter, (I have one that works), and use Pinebook Pro's other USB 3 port for any higher speed peripherals.
