From: Thierry Reding <treding@xxxxxxxxxx>
This adds a device tree for the Jetson Orin NX module, which is Jetson
AGX Orin's little sibling with 6 or 8 ARM Cortex-A78AE cores, an Ampere
GPU (1024 GPU and 32 tensor cores) and a number of accelerators for
machine learning, image processing and more.
The Jetson Orin NX comes with either 8 or 16 GiB of 128-bit LPDDR5 and
supports NVME for mass storage.

Changes in v3:
- split out P3767 DTS include to allow sharing with Jetson Orin Nano
Changes in v2:
- add SPI flash and SD card to make UEFI happy
