   1 device-tree bindings for rockchip VPU codec
   2
   3 Rockchip (Video Processing Unit) present in various Rockchip platforms,
   4 such as RK3288, RK3328 and RK3399.
   5
   6 Required 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
