+Device-Tree bindings for SUNXI video engine found in sunXi SoC family
+
+Required properties:
+- compatible : "allwinner,sun4i-a10-video-engine";
+- memory-region : DMA pool for buffers allocation;
+- clocks : list of clock specifiers, corresponding to
+ entries in clock-names property;
+- clock-names : should contain "ahb", "mod" and "ram" entries;
+- resets : phandle for reset;
+- interrupts : should contain VE interrupt number;
+- reg : should contain register base and length of VE.
+
+Example:
+
+reserved-memory {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ ve_reserved: cma {
+ compatible = "shared-dma-pool";
+ reg = <0x43d00000 0x9000000>;
+ no-map;
+ linux,cma-default;
+ };
+};
+
+video-engine {
+ compatible = "allwinner,sun4i-a10-video-engine";
+ memory-region = <&ve_reserved>;
+
+ clocks = <&ahb_gates 32>, <&ccu CLK_VE>,
+ <&dram_gates 0>;
+ clock-names = "ahb", "mod", "ram";
+
+ assigned-clocks = <&ccu CLK_VE>;
+ assigned-clock-rates = <320000000>;
+
+ resets = <&ccu RST_VE>;
+
+ interrupts = <53>;
+
+ reg = <0x01c0e000 4096>;
+};
