[PATCH v2 14/14] arm64: tegra: Initial Tegra234 VDK support
Thierry Reding

Thu Sep 17 06:07:52 EDT 2020
From: Thierry Reding <treding at nvidia.com>
The NVIDIA Tegra234 VDK is a simulation platform for the Orin SoC. It
supports a subset of the peripherals that will be available in the final
chip and serves as a bootstrapping platform.
Signed-off-by: Thierry Reding <treding at nvidia.com>

Changes in v2:
- drop compatible string for BPMP shared memory nodes
- add fallback compatible string for RTC
