I took your branch, booted AM5 EVM (I see you had the hack dts patch in your branch), and:

How am I expected to sneak patches in if you test them ? :-)
This has been introduced by a recent rebase, and I've only tested the series on the pandaboard since then. It looks like the problem comes from

drm/panel: simple: Add ability to override typical timingwhich breaks our out-of-tree DT. As a short term fix I can simply drop the panel timings from DT, but I think this issue can affect more
So just removing the timings from the panel's node should be enough? Still crashing for me, although the panel warning goes away.
My bad, you also need the following patch that I will include in v3.
Thanks, but I guess I need something more:
drivers/gpu/drm/panel/panel-simple.c:2384:3: error: ‘const struct panel_desc’ has no member named ‘connector_type’ .connector_type = DRM_MODE_CONNECTOR_DPI,
