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. 7 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.
