-/**
- * typedef union ofnode_union ofnode - reference to a device tree node
- *
- * This union can hold either a straightforward pointer to a struct device_node
- * in the live device tree, or an offset within the flat device tree. In the
- * latter case, the pointer value is just the integer offset within the flat DT.
- *
- * Thus we can reference nodes in both the live tree (once available) and the
- * flat tree (until then). Functions are available to translate between an
- * ofnode and either an offset or a `struct device_node *`.
- *
- * The reference can also hold a null offset, in which case the pointer value
- * here is NULL. This corresponds to a struct device_node * value of
- * NULL, or an offset of -1.
- *
- * There is no ambiguity as to whether ofnode holds an offset or a node
- * pointer: when the live tree is active it holds a node pointer, otherwise it
- * holds an offset. The value itself does not need to be unique and in theory
- * the same value could point to a valid device node or a valid offset. We
- * could arrange for a unique value to be used (e.g. by making the pointer
- * point to an offset within the flat device tree in the case of an offset) but
- * this increases code size slightly due to the subtraction. Since it offers no
- * real benefit, the approach described here seems best.
- *
- * For now these points use constant types, since we don't allow writing
- * the DT.
- *
- * @np: Pointer to device node, used for live tree
- * @of_offset: Pointer into flat device tree, used for flat tree. Note that this
- * is not a really a pointer to a node: it is an offset value. See above.
