You could add another ToDo bullet point of:
- USB3 via USB-C
I have done some of this:
- Driver for FUSB302B USB-C power controller (from OpenBSD).
- Driver for RK3399 USB-C phy (from OpenBSD) plus extra clocks.
- Add support for interrupts to the RK3399 GPIO driver.
The RK3399 USB-C phy driver doesn't currently handle multiplexing HDMI
onto the external port, someone would need to extend it to deal with
this, the equivalent Linux driver might help.
Haven't got the FUSB302B driver to detect power change events yet, am
guessing may need to setup the start conditions for the chip differently
in terms of pullups or pulldowns..
I could commit the partially working drivers for other people to try but
not add them to GENERIC64 yet.
