[PATCH 0/4] Properly support FriendlyElec HD702E

Hi all,
I've been using the HD702E LCD/touchscreen on my NanoPC-T4 for a few
years using my own DT with the "simple-panel" binding, but now we have
upstream overlays I figured it's about time to try doing it properly.
The screen itself doesn't seem to want to work as a generic "edp-panel",
as it appears the EDID isn't readable until after the whole lot is
enabled - I'm guessing this might be to do with the Analogix driver's
force-hpd behaviour - but since we do already have the legacy data, it
doesn't seem unreasonable to keep using it.
Thanks,
Robin.
