Comment 52 for bug 1944397

@jawn-smith, I'm using this display:
https://www.waveshare.com/5.5inch-hdmi-amoled-with-case.htm

with this cmdline.txt:
console=tty1 root=LABEL=writable rootfstype=ext4 rootwait quiet splash video=HDMI-A-1:1080x1920M@60,rotate=90,panel_orientation=right_side_up drm.edid_firmware=edid/Waveshare5.5Amoled4.bin fbcon=rotate:1 fsck.mode=force fsck.repair=yes

and that edid file is attached.
