Everything required to populate NVIDIA Tegra devices from the device tree. This patch adds a new DT_MACHINE_DESC() which matches against a tegra20 device tree. So far it only registers the on-chip devices, but it will be refined in follow on patches to configure clocks and pin IO from the device tree also.
