[PATCH v3 08/10] OF: remove device and resource pointer from struct device_node

[Sebastian Hesselbarth]

struct device_node has its own resources and a pointer to associated
device_d. With recent platform related OF code, we can convert the
only user of it and remove those pointers from struct device_node.
