+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:
+ - vde
+
+Example:
+

+ compatible = "nvidia,tegra20-vde";
+ reg = <0x6001a000 0x1000 /* Syntax Engine */

+ 0x6001ca00 0x100 /* Video DMA */
+ 0x6001d800 0x300 /* Video frame controls */>;
+ reg-names = "sxe", "bsev", "mbe", "ppe", "mce",
+ "tfe", "ppb", "vdma", "frameid";
+ iram = <&vde_pool>; /* IRAM region */
