arm64: tegra: Add support for Jetson Xavier NX
Add the device-tree source files for the Tegra194 Jetson Xavier NX Developer Kit. The Xavier NX Developer Kit consists of a small form factor system-on-module (SOM) board (part number p3668-0000) and a carrier board (part number p3509-0000). The Xavier NX Developer Kit SOM features a micro-SD card slot, however, there is also a variant of the SOM available that features a 16GB eMMC. Given that the carrier board can be used with the different SOM variants, that have different part numbers, both the compatible string and file name of the device-tree source file for the Developer Kit is a concatenation of the SOM and carrier board part numbers. Based on some initial work by Thierry Reding <treding@nvidia.com>. Signed-off-by: Jon Hunter <jonathanh@nvidia.com> Signed-off-by: Thierry Reding <treding@nvidia.com>
