Display is working in both X and wayland (tested with weston and XFCE).
Not tried with osk-sdl yet, charging-sdl seems to work fine.
USB networking and SSH is working too.
Camera subsystem disabled to prevent bootloops. This device brings its

is used at build time (patched to make it work properly).
[skip ci]: already built in CI successfully
