# INFO this is for the kukui krane chromebook, i.e. the lenovo duet chromebook and it
#      might also work on the rk3399 based gru bob and gru kevin chromebooks
# IMPORTANT: this is work in progress and not everything is working
# status: 5.10.1 works with wayland and latest mesa on krane, xorg does not work
#         5.10.20+ works with wayland and xorg with latest mesa on krane, not working on elm
#         5.13.0 works ok for me on krane and juniper as long as the gpu is not used
#                panfrost has to be a module as otherwise the juniper drm bridge does not get edid info ...
# credits go to https://gitlab.freedesktop.org/icecream95/duet-kernel.git
