If "name" is not specified, a default "reg" is used. Cell sizes are determined by parent's #address-cells and size-cells. This function may insert data into the blob, and will therefore change the offsets of some existing nodes. returns: 0, on success -FDT_ERR_BADLAYOUT, -FDT_ERR_BADMAGIC, -FDT_ERR_BADNCELLS, if the node has a badly formatted or invalid #address-cells property -FDT_ERR_BADOFFSET, nodeoffset did not point to FDT_BEGIN_NODE tag -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_BADVERSION, -FDT_ERR_BADVALUE, addr or size doesn't fit to respective cells size -FDT_ERR_NOSPACE, there is insufficient free space in the blob to contain a new property -FDT_ERR_TRUNCATED, standard meanings | |

fdt_add_subnode - creates a new node @fdt: pointer to the device tree blob @parentoffset: structure block offset of a node fdt_add_subnode() creates a new node as a subnode of the node at structure block offset parentoffset, with the given name (which should include the unit address, if any). This function will insert data into the blob, and will therefore change the offsets of some existing nodes. returns: structure block offset of the created nodeequested subnode (>=0), on success -FDT_ERR_NOTFOUND, if the requested subnode does not exist -FDT_ERR_BADOFFSET, if parentoffset did not point to an FDT_BEGIN_NODE tag -FDT_ERR_EXISTS, if the node at parentoffset already has a subnode of the given name -FDT_ERR_NOSPACE, if there is insufficient free space in the blob to contain the new node -FDT_ERR_NOSPACE -FDT_ERR_BADLAYOUT -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_TRUNCATED, standard meanings. | |

fdt_for_each_subnode - iterate over all subnodes of a parent
@node: child node (int, lvalue) @fdt: FDT blob (const void *) @parent: parent node (int)
This is actually a wrapper around a for loop and would be used like so:
fdt_for_each_subnode(node, fdt, parent) { Use node ... }
if ((node < 0) && (node != -FDT_ERR_NOTFOUND)) { Error handling }
Note that this is implemented as a macro and @node is used as iterator in the loop. The parent variable be constant or even a literal.

fdt_parent_offset() locates the parent node of a given node (that is, it finds the offset of the node which contains the node at nodeoffset as a subnode).
NOTE: This function is expensive, as it must scan the device tree structure from the start to nodeoffset, twice.
returns: structure block offset of the parent of the node at nodeoffset (>=0), on success -FDT_ERR_BADOFFSET, nodeoffset does not refer to a BEGIN_NODE tag -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, standard meanings

fdt_node_offset_by_prop_value() returns the offset of the first node after startoffset, which has a property named propname whose value is of length proplen and has value equal to propval; or if startoffset is -1, the very first such node in the tree.
To iterate through all nodes matching the criterion, the following idiom can be used: offset = fdt_node_offset_by_prop_value(fdt, -1, propname, propval, proplen); while (offset != -FDT_ERR_NOTFOUND) { // other code here offset = fdt_node_offset_by_prop_value(fdt, offset, propname, propval, proplen); }
Note the -1 in the first call to the function, if 0 is used here instead, the function will never locate the root node, even if it matches the criterion.
