[PATCH 1/2] dt-bindings: arm: tegra: Document Jetson AGX Thor DevKit

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

The Jetson AGX Thor Developer Kit uses the same module (P3834) as the
P3971 reference platform but a slightly different carrier board (P4071).

[PATCH 2/2] arm64: tegra: Add Jetson AGX Thor Developer Kit support

[Thierry Reding]

From: Thierry Reding <treding@nvidia.com>

Add basic support for the Jetson AGX Thor Developer Kit. It's quite
similar to the existing reference platform but has a slightly different
carrier board with different mass storage options and I/O.
