I thought I'd test this, so I took

commit 6d028043b55e54f48fbdf62ea8ce11a4ad830cac
    Add linux-next specific files for 20190830

Series (and the other two patches you sent around it) applies ok, but
the result does not boot.

Hmm.

I guess I'll need to resurrect the serial port cable.

Best regards,

Hmm. Maybe I'm just having problem with the backlight. I do see
regulator failure:

But I get login prompt on the serial. And after I do:

root@devuan:/sys/class/leds/lm3532::backlight# echo 255 > brightness

I can even see X are running.

Good so far :-).
