RESOLVED: a64-pine64+ goodix touchscreen (i2c) fails to load on reboot
Armbianmonitor:

5.10.4-sunxi64 pine64 board with goodix 7" mipi-dsi LCD touchscreen.
The LCD output is working fine across reboots after enabling the dt overlay using armbian-config.
For the touchscreen, I have added "goodix" to /etc/modules and the digitizer works fine from all cold boots:
~$ dmesg | grep -i goodix
[ 5.836601] Goodix-TS 1-005d: supply VDDIO not found, using dummy regulator
[ 5.843605] G
This is resolved now. After reading https://www.raspberrypi.org/forums/viewtopic.php?t=216901 I created the following systemd service file:
Unit]
Description=unload the goodix driver ahead of reboots to allow it to properly load again when the system restarts
[Service]
ExecStop=/sbin/rmmod goodix
Type=oneshot
RemainAfterExit=true
[Install]
WantedBy=multi-user.target
System now comes up with working touchscreen every time:)
