I have changed the way the patches are generated a bit. Instead of using orange-pi branch from megous tree for 6.6 kernel, I have used the following kernel branches a83t-suspend, af8133j, anx, audio, axp, cam, drm, err, fixes, mbus, modem, opi3, pb, pinetab, pp, ppkb, samuel, speed, tbs-a711, ths These branches were carefully chosen to include only allwinner related patches and remove importing of the rockchip related patches into the allwinner kernel. Following patches are modified to fix patch application failure - patches.armbian/arm64-dts-sun50i-h616-orangepi-zero2-reg_usb1_vbus-status-ok.patch - patches.armbian/arm64-dts-sun50i-h616-orangepi-zero2-Enable-GPU-mali.patch - patches.armbian/arm64-dts-allwinner-h616-Add-efuse_xlate-cpu-frequency-scaling-v1_6_2.patch - patches.armbian/arm64-dts-allwinner-h616-LED-green_power_on-red_status_heartbeat.patch - patches.armbian/arm64-dts-allwinner-overlay-Add-Overlays-for-sunxi64.patch - patches.armbian/arm64-dts-sun50i-h616-bigtreetech-cb1.patch Following patches are modified because of kernel api change to fix compilation failure - patches.armbian/drv-gpu-drm-sun4i-Add-HDMI-audio-sun4i-hdmi-encoder.patch - patches.armbian/drv-of-Device-Tree-Overlay-ConfigFS-interface.patch
