Thanks for getting this driver done. I need help a bit using
this though.. What's the glue to the drm driver?

I can control the backlight brightness just fine via /sys, and
backlight shows up as the trigger in /sys/class/leds/lm3532:backlight,
but /sys/class/backlight is empty and looks like drm can't find it.

Do I need to enable some additional driver(s) to get this to work
with the drm driver?

Regards,

Tony
