- delivered to multiple devices and to be propogated from device to

- Where <name> is the name of the template device, <unit> is a
- textual specification of the devices unit address (that is
- converted into a numeric form by the devices parent) and <args> are
- optional additional information to be passed to the device-template
- when it creates the device.
-
- Properties:
-
- Properties are specified in a similar way to devices except that
- the last element on the path (which would have been the device) is
- the property name. This path is then followed by the property
- value. Unlike OpenBoot, the property values in the device tree are
- strongly typed.
-
- String property:
-
- <property-name> " " <text>
- <property-name> " " "\"" <text>
-
- Boolean property:
-
- <property-name> " " [ "true" | "false" ]
- Integer property or integer array property:
-
- <property-name> " " <number> { <number> }
-
- Phandle property:
-
- <property-name> " " "&" <path-to-device>
-
- Ihandle property:
-
- <property-name> " " "*" <path-to-device-to-open>
-
- Duplicate existing property:
-
- <property-name> " " "!" <path-to-original-property>
-
-
- In addition to properties, the wiring of interrupts can be
- specified:
-
- Attach interrupt <line> of <device> to <controller>:
-
- <device> " " ">" <my-port> <dest-port> <dest-device>
-
-
- Once created, a device tree can be traversed in various orders: */
