As stated in the topic the new Orange Pi Zero LTS reports incorrect system temps (likely due to 16bit overflow if I were to guess):
~$ cat /sys/devices/virtual/thermal/thermal_zone0/temp
-2178

on my OPi Zero (non LTS) I got "working" temps with kernel 5.2.2:
Debian Buster with Armbian Linux 5.2.2-sunxi
