1device-tree bindings for rockchip VPU codec
2
3Rockchip (Video Processing Unit) present in various Rockchip platforms,
4such as RK3288 and RK3399.
5
6Required properties:
7- compatible: value should be one of the following
8 "rockchip,rk3288-vpu";
9 "rockchip,rk3399-vpu";
10- interrupts: encoding and decoding interrupt specifiers
11- interrupt-names: should be "vepu" and "vdpu"
12- clocks: phandle to VPU aclk, hclk clocks
13- clock-names: should be "aclk" and "hclk"
14- power-domains: phandle to power domain node
15- iommus: phandle to a iommu node

17Example:
18SoC-specific DT entry:
19 vpu: video-codec@ff9a0000 {
20 compatible = "rockchip,rk3288-vpu";
21 reg = <0x0 0xff9a0000 0x0 0x800>;
22 interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,
23 <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>;
24 interrupt-names = "vepu", "vdpu";
25 clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>;
26 clock-names = "aclk", "hclk";
27 power-domains = <&power RK3288_PD_VIDEO>;
28 iommus = <&vpu_mmu>;
29 };
