   1 Rockchip IOMMU
   2 ==============
   3
   4 A Rockchip DRM iommu translates io virtual addresses to physical addresses for
   5 its master device.  Each slave device is bound to a single master device, and
   6 shares its clocks, power domain and irq.
   7
   8 Required properties:
   9 - compatible      : Should be "rockchip,iommu"
  10 - reg             : Address space for the configuration registers
  11 - interrupts      : Interrupt specifier for the IOMMU instance
  12 - interrupt-names : Interrupt name for the IOMMU instance
  13 - #iommu-cells    : Should be <0>.  This indicates the iommu is a
  14                     "single-master" device, and needs no additional information
  15                     to associate with its master device.  See:

  20         vopl_mmu: iommu@ff940300 {
  21                 compatible = "rockchip,iommu";
  22                 reg = <0xff940300 0x100>;
  23                 interrupts = <GIC_SPI 16 IRQ_TYPE_LEVEL_HIGH>;
  24                 interrupt-names = "vopl_mmu";
  25                 #iommu-cells = <0>;
  26         };
