1device-tree bindings for rockchip VPU codec
2
3Rockchip (Video Processing Unit) present in various Rockchip platforms,
4such as RK3288, RK3328 and RK3399.
5
6Required properties:
7- compatible: value should be one of the following
8 "rockchip,rk3288-vpu";
9 "rockchip,rk3328-vpu";
10 "rockchip,rk3399-vpu";
11- interrupts: encoding and decoding interrupt specifiers
12- interrupt-names: should be
13 "vepu", "vdpu" on RK3288 and RK3399,
14 "vdpu" on RK3328.
15- clocks: phandle to VPU aclk, hclk clocks
16- clock-names: should be "aclk" and "hclk"
17- power-domains: phandle to power domain node
18- iommus: phandle to a iommu node
19
20Example:
21SoC-specific DT entry:
22 vpu: video-codec@ff9a0000 {
23 compatible = "rockchip,rk3288-vpu";
24 reg = <0x0 0xff9a0000 0x0 0x800>;
25 interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,
26 <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>;
27 interrupt-names = "vepu", "vdpu";
28 clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>;
29 clock-names = "aclk", "hclk";
30 power-domains = <&power RK3288_PD_VIDEO>;
31 iommus = <&vpu_mmu>;
32 };
33
34 vpu: video-codec@ff350000 {
35 compatible = "rockchip,rk3328-vpu";
36 reg = <0x0 0xff350000 0x0 0x800>;
37 interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>;
38 interrupt-names = "vdpu";
39 clocks = <&cru ACLK_VPU>, <&cru HCLK_VPU>;
40 clock-names = "aclk", "hclk";
41 power-domains = <&power RK3328_PD_VPU>;
42 iommus = <&vpu_mmu>;
43 };
