+device-tree bindings for rockchip VPU codec
+
+Rockchip (Video Processing Unit) present in various Rockchip platforms,
+such as RK3288 and RK3399.
+
+Required properties:
+- compatible: value should be one of the following
+ "rockchip,rk3288-vpu";
+ "rockchip,rk3399-vpu";
+- interrupts: encoding and decoding interrupt specifiers
+- interrupt-names: should be "vepu" and "vdpu"
+- clocks: phandle to VPU aclk, hclk clocks
+- clock-names: should be "aclk" and "hclk"
+- power-domains: phandle to power domain node
+- iommus: phandle to a iommu node
+
+Example:
+SoC-specific DT entry:
+ vpu: video-codec@ff9a {
+ compatible = "rockchip,rk3288-vpu";
+ reg = <0x0 0xff9a 0x0 0x800>;
+ interrupts = ,
+;
+ interrupt-names = "vepu", "vdpu";
+ clocks = < ACLK_VCODEC>, < HCLK_VCODEC>;
+ clock-names = "aclk", "hclk";
+ power-domains = < RK3288_PD_VIDEO>;
+ iommus = <_mmu>;
+ };
