Function Documentation

_fdt_node_end_offset()

int _fdt_node_end_offset	(	void *	fdt,
		int	offset
	)

Definition at line 97 of file fdt_wip.c.

fdt_nop_node()

int fdt_nop_node	(	void *	fdt,
		int	nodeoffset
	)

fdt_nop_node - replace a node (subtree) with nop tags @fdt: pointer to the device tree blob @nodeoffset: offset of the node to nop

fdt_nop_node() will replace a given node's representation in the blob, including all its subnodes, if any, with FDT_NOP tags, effectively removing it from the tree.

This function will alter only the bytes in the blob which contain the node and its properties and subnodes, and will not alter or move any other part of the tree.

returns: 0, on success -FDT_ERR_BADOFFSET, nodeoffset did not point to FDT_BEGIN_NODE tag -FDT_ERR_BADMAGIC, -FDT_ERR_BADVERSION, -FDT_ERR_BADSTATE, -FDT_ERR_BADSTRUCTURE, -FDT_ERR_TRUNCATED, standard meanings
