 * So I tested the 1:1:1 topology on rc and it looks better than before now. I don't see any errors related to panel at all, and hwtest gives me

```

So far, so good. Panel however isn't outputting anything. But when I do `cat /sys/class/backlight/ae94000.dsi.0/actual_brightness`, I start seeing errors in dmesg:

the last part just keeps repeating and is fairly familiar now, that's the one I always got.
