2014-11-04of: Eliminate of_allnodes listGrant Likely1-2/+1
The device tree structure is composed of two lists; the 'allnodes' list which is a singly linked list containing every node in the tree, and the child->parent structure where each parent node has a singly linked list of children. All of the data in the allnodes list can be easily reproduced with the parent-child lists, so of_allnodes is actually unnecessary. Remove it entirely which saves a bit of memory and simplifies the data structure quite a lot.

2010-10-13of/promtree: add package-to-path support to pdtAndres Salomon1-0/+3
package-to-path is a PROM function which tells us the real (full) name of the node. This provides a hook for that in the prom ops struct, and makes use of it in the pdt code when attempting to determine a node's name. If the hook is available, try using it (falling back to looking at the "name" property if it fails).

2010-10-13of/promtree: add of_pdt namespace to pdt codeAndres Salomon1-1/+1
For symbols still lacking namespace qualifiers, add an of_pdt_ prefix. Signed-off-by: Andres Salomon <dilinger@queued.net> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-10-13of/promtree: no longer call prom_ functions directly; use an ops structureAndres Salomon1-1/+19
Rather than assuming an architecture defines prom_getchild and friends, define an ops struct with hooks for the various prom functions that pdt.c needs. This ops struct is filled in by the arch-(and sometimes firmware-)specific code, and passed to of_pdt_build_devicetree. Update sparc code to define the ops struct as well.

2010-10-11of/promtree: make drivers/of/pdt.c no longer sparc-onlyAndres Salomon1-0/+24
Clean up pdt.c: - make build dependent upon config OF_PROMTREE - #ifdef out the sparc-specific stuff - create pdt-specific header Signed-off-by: Andres Salomon <dilinger@queued.net> Acked-by: David S. Miller <davem@davemloft.net> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
