   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
