-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>;
