From 3f9efbbe57bc6e999f6f4d389da289f2733f0261 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Mon, 13 Jul 2020 17:17:01 +0100 Subject: [PATCH] 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 .
