Name

of_fdt_unflatten_tree — Create expanded device tree (EDT)

Synopsis

void * of_fdt_unflatten_tree (const unsigned long * blob,
 struct device_node * dad,
 struct device_node ** mynodes);
 

Arguments

blob

Pointer to flattened device tree (FDT)

dad

NULL or pointer to device tree node to attach new tree to

mynodes

Pointer used to return the expanded device tree (EDT)

Description

Create an expanded device tree (EDT) from the flattened device tree (FDT) blob. The name and type fields of the nodes will be populated so the normal device-tree walking functions can be used.

If dad is NULL, the path of the root of the EDT will /.

If dad is not NULL that is probably an error. This usage is deprecated. The newly created tree will be grafted onto node dad. See notes about dad in unflatten_dt_nodes for more details.

Return

Pointer to the expanded device tree (EDT) on success. NULL on error.
