In such cases the single + address cell corresponds to the master device's ID. In some cases more than + one cell can be required to represent a single master ID. +- #iommu-cells = <4>: Some IOMMU devices allow the DMA window for masters to + be configured. The first cell of the address in this may contain the master + device's ID for example, while the second cell could contain the start of + the DMA window for the given device. The length of the DMA window is given + by the third and fourth cells. + +Note that these are merely examples and real-world use-cases may use different +definitions to represent their individual needs. Always refer to the specific +IOMMU binding for the exact meaning of the cells that make up the specifier. + + +IOMMU master node: +================== + +Devices that access memory through an IOMMU are called masters. A device can +have multiple master interfaces (to one or more IOMMU devices). + +Required properties: +-------------------- +- iommus: A list of phandle and IOMMU specifier pairs that describe the IOMMU + master interfaces of the device. One entry in the list describes one master + interface of the device. + +When an "iommus" property is specified in a device tree node, the IOMMU will +be used for address translation. If a "dma-ranges" property exists in the +device's parent node it will be ignored. An exception to this rule is if the +referenced IOMMU is disabled, in which case the "dma-ranges" property of the +parent shall take effect. Note that merely disabling a device tree node does +not guarantee that the IOMMU is really disabled since the hardware may not +have a means to turn off translation. But it is invalid in such cases to +disable the IOMMU's device tree node in the first place because it would +prevent any driver from properly setting up the translations. + + +Notes: +====== + +One possible extension to the above is to use an "iommus" property along with +a "dma-ranges" property in a bus device node (such as PCI host bridges). This +can be useful to describe how children on the bus relate to the IOMMU if they +are not explicitly listed in the device tree (e.g. PCI devices).
