Hello everyone.
FYI
After mali power domain was enabled
Added gpu (Mali) dts entry for Banana PI R2 Pro. · frank-w/BPI-Router-Linux@c4e40f1 · GitHub
Gpu confirmed working:
alex@bpi-r2pro ~ $ glxinfo | grep OpenGL

Also in order to start Xorg successfully, AutoAddGPU flag should be turned off (the same way as for BPI-R2). In my case next additional config works:
bpi-r2pro ~ # cat /etc/X11/xorg.conf.d/40-serverflags.conf
Section "ServerFlags"
Option "AutoAddGPU" "off"
EndSection
