Jetpack 5.0 DP dtsi error

Building the Jetpack 5.0 DP unmodified source is throwing a dtsi error. Is there a work around? Is there a patch fix in progress?

Note, this is using the bootlin 9.3 gcc toolchain and “stock”, “as-shipped” unmodified sources. The tegra_defconfig has not been modified or changed. Here is the console output for the dtbs build failure.

I drilled down and found the root of this dtsi include problem. The Jetpack 5.0 DP as-released hardware source tree (directory structure) doesn’t match the Makefile DTC_INCLUDE path for t23x. Either the hardware source tree needs to be restructured or DTC Makefile needs to be tweaked. Nvidia needs to release a patch.
