Hi Eric,

thanks for response, but it does not fix the issue for me. hdmi on mt7623 =
is DPI not DSI. There is already a mt7623 specific routing-table defined (=
one for DPI/HDMI and one for external=3DDSI/MIPI):

https://elixir.bootlin.com/linux/latest/source/drivers/gpu/drm/mediatek/mt=
k_drm_drv.c#L74

maybe it can be included or compared with the "default" route?

regards Frank
