to give me a pointer to the node name for node tags and property name for property tags. Now that I have it working, it would be trivial to change the calls to _fdt_next_tag() to instead call fdt_next_tag() passing NULL for the new fourth parameter **namep. ;-)
The reason I need it, I'm printing an unknown tree by stepping through the tree discovering the node and property names. I need to have fdt_next_tag() return the *name* of the node/property as well as the tag so that I can print and indent for nodes or look up the property value and print the name=value combination.
Hrm. And it returns NULL for tags without a name?
I was unable to generate a tag without a name using dtc (other than the root node). It should/would return null, which would be a problem. :-/
I was thinking more of tag types which don't have a name, to wit, FDT_END_NODE and FDT_NOP.
fdt_next_tag() returns the tag, so it returns FDT_END_NODE or FDT_NOP and, presumably, the caller would know there is no name associated with those tags. Setting the name pointer *namep to NULL would be good paranoia, however.
