| 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>; |
| }; |
