1bbfc41d27 arm64: tegra: Add 35°C trip point for Jetson Orin NX/Nano 
It turns out that these devices can get quite hot to the touch with the
standard cooling configuration, so add another trip point at 35°C along
with a cooling map to help keep the system reasonably cool at very low
system load.

50b6a5db24 [UPSTREAM v6.5]: arm64: tegra: Enable thermal support on Jetson Orin NX 
Enable the TJ thermal zone and hook up cooling maps for the PWM-
controlled fan and two trip points.

This also removes a duplicate definition of the PWM fan and changes its
cooling levels. This should have no effect, though, because the fan
wasn't previously connected to anything and by default would be turned
off at probe time.

884c9fafe5 UPSTREAM: arm64: tegra: Add Jetson Orin NX support 
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.
