Mainline kernel not working (no screen)
#2
There are still patches which haven't made it to mainline yet, I don't expect the phone to be fully functional before 5.9 at least.

The main issue regarding the display is that CONFIG_DRM_PANEL_XINGBANGDA_XBD599 (that's the one for v1.1+, the other was for the devkit) has been renamed to CONFIG_DRM_PANEL_SITRONIX_ST7703 since 5.7.
I suggest you start with a 5.7 defconfig, either from Mobian's repo or the one provided by Pine64.

Anyway, based on your defconfig diff, I assume camera, wifi and modem audio won't work at all with mainline (due to the lack of SUN6I_CSI, RTL8723CS_NEW and SND_SOC_EC25).
But you should be able to boot and use most of the features (including mobile data) without these Wink

FWIW, I'm a huge fan of debos when it comes to building custom debian images, I suggest you have a look here, with a few tweaks you'll be able to make a pure Debian image in no time Wink
