This function retrieves a node pointer based on the "device_type" property of the node. This is used by device tree update functions in PPC support.

| * Add configurability via devicetreeSascha Hauer2013-07-184-0/+264
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the possibility to configure the place for the environment from the devicetree and to partition devices from the devicetree. Configuration has the general form of devices with a regular compatible property. This allows to later add additional drivers or drivers with different behaviour (for example to add support for redundant environment). The configuration is all in the /chosen/barebox/ hierarchy of the devicetree. This separates the configuration from the hardware description. Also it makes it possible to store the configuration in a completely separate devicetree (or devicetree overlay). For the same reason all configuration is done using nodepathes rather than phandles.

|/ | | | | | | | | | | | | of_find_node_by_name suffers from infinite looping, because it does not check for root node of the tree iterated over. This fixes this by checking for node->parent to determine whether the last node has been reached. Since of_tree_for_each_node does not iterate over the whole tree, but only over the remaining nodes, rename it to of_tree_for_each_node_from.
