[ I don't have a sun4i-hdmi, but I do have a sun4i-drm-hdmi, so I assume
this was just a typo. ]
I just did:
modprobe -r sun4i-drm
modprobe sun4i-tcon
modprobe sun4i-backend
modprobe sun4i-drm-hdmi
modprobe sun4i-drm
and all four modules loaded fine (according to `lsmod`), but I get
nothing in dmesg, and /sys/class/drm still only contains `version` :-(
Also, what could cause those modules not to be loaded automatically?
