Port the tree from L4T R36.5.0 / JetPack 6.2.2 to L4T R39.2.1 / JetPack 7.2.1 (kernel 6.8, Ubuntu 24.04 rootfs, Crosstool-NG gcc 13.2). Rebased onto current main. Camera/multimedia debs moved from the t234 pool to som on R39; the Argus 36.4.4 pin is JP6-only and is replaced with the matching 39.2.1 stamp.

JetPack 7 / kernel-noble dropped gpio_cansleep, changed i2c_driver.probe to take only the client, and made i2c_driver.remove return void. Match NVIDIA's nv_imx219 compat macros so the overlay still builds on 5.15 and 6.8.
R39 public_sources adds nvidia_unified_gpu_display_driver_source.tbz2 (unifiedgpudisp). Skipping it makes `make modules` fail, which also skipped `make dtbs`. R39 writes DTBs to build/nvidia-public/devicetree/generic-dtbs, not the R36 kernel-devicetree path — so kernel/dtb never received the ARK camera overlays and flash.sh aborted.

Build notes that were required to get here (already on this branch):
Not provisioned: ARK-OS (no noble package yet). Camera stack is the 39.2.1 stamp, not the JP6 Argus 36.4.4 pin. |
