1Rockchip IOMMU
2==============
3
4A Rockchip DRM iommu translates io virtual addresses to physical addresses for
5its master device.  Each slave device is bound to a single master device, and
6shares its clocks, power domain and irq.

8Required 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>;
