Khadas Edge V5 seems to have extra gigabit LAN and PCIE, not present in Khadas Edge. So it’s dts for LibreELEC can perhaps just get changes from mainline patch @numbqq posted.
Also ‘vopl’ must be disabled for 4K playback to work correctly.
I hope the mainline driver for the wifi for Khadas Edge V5 will also be able to be build in future.
