21  * ofnode - reference to a device tree node
27  * Thus we can reference nodes in both the live tree (once available) and the
31  * The reference can also hold a null offset, in which case the pointer value
63  * ofprop - reference to a property of a device tree node
65  * This struct hold the reference on one property of one node,
69  * Thus we can reference arguments in both the live tree and the flat tree.
71  * The property reference can also hold a null reference. This corresponds to
90  * This cannot be called if the reference contains an offset.
92  * @node: Reference containing struct device_node * (possibly invalid)
107  * This cannot be called if the reference contains a node pointer.
109  * @node: Reference containing offset (possibly invalid)
124  * @return true if the reference contains a valid ofnode, false if it is NULL
138  * @return reference to the associated DT offset
156  * @return reference to the associated node pointer
168  * ofnode_is_np() - check if a reference is a node pointer
174  * @node: reference to check (possibly invalid)
175  * @return true if the reference is a live node pointer, false if it is a DT

571  * Get reference to the first property of the node, it is used to iterate
575  * @prop: place to put argument reference
581  * ofnode_get_next_property() - get the reference of the next property
583  * Get reference to the next property of the node, it is used to iterate
586  * @prop: reference of current argument and place to put reference of next one
594  * Get value for the property identified by the provided reference.
596  * @prop: reference on property
