Hi Greg,
Fedora 36 has switched from efifb to simpledrm as the pre-native-GPU driver fb provider and the lack of this patch is causing issues for devices with non up-right mounted LCD panels (1), can you please add this to the 5.17 stable series?
Regards,
Hans

Hans de Goede (1): drm/simpledrm: Add "panel orientation" property on non-upright mounted LCD panels
drivers/gpu/drm/tiny/simpledrm.c | 3 +++ 1 file changed, 3 insertions(+)
commit 94fa115f7b28a3f02611499175e134f0a823b686 upstream.
Some devices use e.g. a portrait panel in a standard laptop casing made for landscape panels. efifb calls drm_get_panel_orientation_quirk() and sets fb_info.fbcon_rotate_hint to make fbcon rotate the console so that it shows up-right instead of on its side.
When switching to simpledrm the fbcon renders on its side. Call the drm_connector_set_panel_orientation_with_quirk() helper to add a "panel orientation" property on devices listed in the quirk table, to make the fbcon (and aware userspace apps) rotate the image to display properly.
