+NVIDIA Tegra Video Decoder Engine
+
+Required properties:
+- compatible : Must contain one of the following values:
+   - "nvidia,tegra20-vde"
+   - "nvidia,tegra30-vde"
+   - "nvidia,tegra114-vde"
+   - "nvidia,tegra124-vde"
+   - "nvidia,tegra132-vde"
+- reg : Must contain an entry for each entry in reg-names.
+- reg-names : Must include the following entries:
+  - sxe
+  - bsev
+  - mbe
+  - ppe
+  - mce
+  - tfe
+  - ppb
+  - vdma
+  - frameid
+- iram : Must contain phandle to the mmio-sram device node that represents
+         IRAM region used by VDE.
+- interrupts : Must contain an entry for each entry in interrupt-names.
+- interrupt-names : Must include the following entries:
+  - sync-token
+  - bsev
+  - sxe
+- clocks : Must include the following entries:
+  - vde
+- resets : Must include the following entries:
