| * of_live_build() - build a live (hierarchical) tree from a flat DT |
| * @fdt_blob: Input tree to convert |
| * @rootp: Returns live tree that was created |
| * Return: 0 if OK, -ve on error |
| int of_live_build(const void *fdt_blob, struct device_node **rootp); |
| * unflatten_device_tree() - create tree of device_nodes from flat blob |
| * Note that this allocates a single block of memory, pointed to by *mynodes. |
| * To free the tree, use free(*mynodes) |
| * unflattens a device-tree, creating the |
| * tree of struct device_node. It also fills the "name" and "type" |
| * pointers of the nodes so the normal device-tree walking functions |
| * @blob: The blob to expand |
| * @mynodes: The device_node tree created by the call |
| * Return: 0 if OK, -ve on error |
