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@ff9a0000 {
compatible = "rockchip,rk3288-vpu";
reg = <0x0 0xff9a0000 0x0 0x800>;
interrupts = <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>,
<GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>;
interrupt-names = "vepu", "vdpu";
clocks = <&cru ACLK_VCODEC>, <&cru HCLK_VCODEC>;
clock-names = "aclk", "hclk";
power-domains = <&power RK3288_PD_VIDEO>;
iommus = <&vpu_mmu>;
};
